Pressure Switches #5068638

Details :

• Flow switch/transmitter for small flows in the foodstuffs industry
• Combination with temperature switch or transmitter possible
• No moving parts in the medium being measured
• Only one medium-contact material
• Simple to use
• Low pressure loss
• Various nominal widths
• Rapid response times for a calorimetric Sensor
• Linearised and temperature compensated

Characteristics :

• The HFK30-FIN flow sensor monitors fluid media. Its compact form combines the measurement tube and converter / counter. The integrated transducer has an analog output (4.20 mA or 0.10 V) and one switching output, which can be configured as a limit switch for monitoring minimal or maximal, or as a frequency output.
• The switching output is designed as a push-pull driver, and can therefore be used both as a PNP or an NPN output. The state of the switching output is signalled with a yellow LED in the switching outlet; the LED has all-round visibility.
• The sensor is configured in the factory, or alternatively this can be done with the aid of the optionally available ECI-3 device configurator (USB interface for PC). A selectable parameter can be modified on the device, with the aid of the magnet clip provided. In this case, the current measured value is saved as the parameter value. Examples of these parameters are the switching value or the metering range end value. The stainless steel electronics housing is rotatable, so it is possible to orient the cable outlet after installation.
• The converter / counter record two process parameters: the flow speed of the medium and its temperature. Both parameters can be assigned to the analog output or to the switching output.

Handling and operation :

• In order to ensure the sensor's maximum insensitivity to interference, the flow should run from bottom to top (best degassing even at the slowest flow speed). Standard crimp connectors, hoses with crush protection, or the crimp connectors provided by HONSBERG can be used for the connection.
• The insulation hoses offer the best possible insulation against the surroundings, and must therefore not be removed.

Accessories :

• ECI-3 device configurator (USB programming adapter)
• Process adapter
• Cable/round plug connector (KH.) see additional information “Accessories”
• External display OMNI-TA or OMNI Remote

Details :

• For foodstuffs use
• Analog output 0/4.20 mA or 0/2.10 V

• Graphical LCD display, backlit (transreflective), can be read in sunlight and in the dark
• Programmable parameters via rotatable, removable ring (programming protection)
• Full metal housing with non-scratch, chemically resistant glass
• Physical unit in the display (selectable)
• Rotatable electronic head for best reading position
• Optionally CIP/SIP-capable (130 °C)
• Connection to USB interface for setting parameters

Characteristics :

• The HFK35-FIN calorimetric sensor measures small fluid flows, and has been designed specially for use in the foodstuffs industry (for the measurement principle, see also "General description: calorimetric sensors").
• The integrated transformer has a backlit graphics LCD display which is very easy to read both in the dark and in bright sunlight. The graphics display allows the presentation of measured values and parameters in a clearly understandable form. The measured values are displayed to 4 places, together with their physical unit, which may also be modified by the user. The electronics have an analog output (4.20 mA or 0.10 V) and two switching outputs, which can be used as limit switches for monitoring minimal or maximal, or as two-point controllers. The switching outputs are designed as push-pull drivers, and can therefore be used both as PNP and NPN outputs. Exceeding limit values is signalled by a red LED which is visible over a long distance, and by a cleartext in the display. The stainless steel case has a hardened non-scratch mineral glass pane. It is operated by a programming ring fitted with a magnet, so there is no need to open the operating controls housing, and its leakproofness is permanently ensured. By turning the ring to right or left, it is simple to modify the parameters (e.g. switching point, hysteresis.). To protect from unintended programming, it can be removed, turned through 180^o and replaced, or completely removed, thus acting as a key.

Wiring :

• Before the electrical installation, it must be ensured that the auxiliary voltage corresponds to the data sheet.
• The switching outputs are self-configuring, depending on whether they are connected as PNP or NPN switches (push-pull).
• It is recommended to use shielded wiring.

Handling and operation :

• In order to ensure the sensor's maximum insensitivity to interference, the flow should run from bottom to top (best degassing even at the slowest flow speed). Standard crimp connectors, hoses with crush protection, or the crimp connectors provided by HONSBERG can be used for the connection.
• The insulation hoses provide the best possible insulation from the environment, and should therefore not be removed.
• It must be ensured that the calming section with the static mixer is not kinked.

Details :

• Very short response time
• High overload protection
• Metering range 1:80
• Low pressure loss
• Compact design

Characteristics :

• The integrated converter / counter make available an electronic switching output (push-pull) with adjustable characteristics (minimum/maximum) and hysteresis, which responds when an adjustable limit is fallen short of or exceeded. If desired, the switching value can be set to the currently existing flow using "teaching".
• Models with analog or pulse output are also available (see separate data sheets). Because the diaphragm only bends, and functions without a bearing, there is almost no friction effect. The movement therefore occurs practically free of hysteresis, and the switching point has very good reproducibility.
• The diaphragm's low bulk results in a short response time. The almost complete covering of the flow cross-section in the neutral position enables a very low response threshold. As soon as the slightest flow exists, the diaphragm is of necessity deflected. The evaluation of the entire flow cross-section means that there are no problems when routing pipes. Run-in and run-out sections are not necessary.

Handling and operation :

• In order to ensure the sensor's maximum insensitivity to interference, the flow should run from bottom to top (best degassing even at the slowest flow speed). Standard crimp connectors, hoses with crush protection, or the crimp connectors provided by HONSBERG can be used for the connection.
• The insulation hoses provide the best possible insulation from the environment, and should therefore not be removed.
• It must be ensured that the calming section with the static mixer is not kinked.

Options :

• Through a range of options, the XF system is flexibly adaptable to very varied requirements.
• Full metal construction - The standard version has a plastic body with a pressure resistance of 16 bar. A metalled body (nickelled brass) with a pressure resistance of 100 bar is optionally available. The higher operating pressure requires a combination with metal connection pieces. Switching value settings in the range 1.80 l/min are possible.
• High temperature - If the full metal model with high temperature sensors is fitted, operation at media temperatures up to 150 °C is possible. Here, the primary sensor element is located in the housing of the measurement unit, while the converter / counter are located away from housing via a 50 cm long heat-resistant cable.
• Resistance to backflows - With forward flows, the diaphragm pushes against an arched end stop, and is undamaged by flow rates which are significantly higher than the intended metering range, or by water hammer. For flows or pressure surges in the reverse direction, in the standard version the diaphragm pushes against a circumferential support ring made of plastic or stainless steel, and almost completely closes the flow cross-section. This causes pressure to build up which can damage the diaphragm. In applications where such conditions can arise (e.g. from elastic hoses to the rear of the measuring equipment) the use of the "resistance to backflows" option is recommended. Here, the support ring is replaced by another arched end stop made of stainless steel, so that the diaphragm is provided with the same overload and pressure surge resistance in the reverse direction as in the forward direction. However, a switching value setting in the reverse direction is not possible.
• Minimum value measurement - For switching ranges up to 6 l/min, the sensitivity and therefore the stability of the measuring system can be increased, and so switching value settings even less than 1 l/min, i.e. from 0.4 l/min become possible. For this, the sensor is installed on the opposite side of the housing. This option is not available for metal housings and models with resistance to backflows.

Handling and operation :

• The device is supplied with connection pieces mounted. These may be removed for the installation in the pipework.
• The sensor can be operated in any location. However, the lowest tendency to contamination occurs when the diaphragm swings from bottom to top. If possible. installation should therefore be made either with flow from bottom to top, or horizontal. In the latter case, the sensor in the minimum value range model (max. 6 l/min, see options) should point downwards; for all other versions it should point upwards. Factory adjustment is made with flow horizontal.
• It should be ensured that the sensor is installed in the direction of the flow arrow. In spite of its low bulk, the diaphragm is very robust; nevertheless it should not be buckled or compressed through force during installation or removal.
• The bolts in the housing pass all the way through it, and must be completely removed if the sensor body is replaced. Afterwards, as normal with a flanged part, the body can be pulled out without loosening the screw connections.
