Deadweight Testersare used for calibration of Pressure gauges and all other Pressure sensing, transmitting & recording instruments. Variety of economical models to suit the industry needs are available in accuracies of 0.2% to 0.1%.

Applications:
Deadweight Testers are used for calibration of pressure gauges and all other Pressure sensing, transmitting and recording instruments having High Accuracy.

Deadweight testers consists of frictionless piston mounted on a rugged base. Its screw type operating system ensures an effortless operation. Rotation of the screw pump produces the pressure which is balanced by precision weighs directly marked in pressure units and stacked on the carrier weight. These testers are designed for precision accuracy of 0.1 % to 0.2%. (Accuracy of 0.01 optional) Unit marking available in Kg/cm2, PSI or Bar etc.

Deadweight Tester is of robust construction with a sturdy steel base having adjustable screws.

Standard Accessories:

• - Accurately calibrated weight.


• - Gauge connection Adapters for 1/8", 1/4", 3/8", 1/2" BSP, 1/2" NPT, M20 x 1.5p on 1/2" BSP Fitment.


• - Pointer Puller and Pointer Punch.


• - Gauge Opener


• - Spirit Level.


• - A set of spanners in a Tool Box.


• - 500ml. oil (SAE 30/40) bottle.


• - One set spare seals.


• - A sturdy carrying case of weights.


• - Dust cover.

Ranges:
The ranges are selectable up to 400 Kg/cm2as tabulated below.

Comparison Testersare used in Laboratories with requirements as test bench for calibration of field mounting gauges as per quality procedure of Industries such as Chemical, Petrochemicals, Pharmaceuticals Bulk Drug and Engineering. These rugged bench mounted testers are manufactured in steel construction, are easy to operate and maintenance free.

These machines can be offered in two different material of constructions and three models :

- STAINLESS STEEL 304 WETTED PARTS, WATER AS PRESSURE MEDIA.
- ALL STAINLESS STEEL CONSTRUCTION, FOR CORROSIVE ATMOSPHERE.

Low pressure class machines are equipped with two feed valves for ease of operation, having Operating Range from 0 to 2000 PSI.

Medium pressure class machines are equipped with only one valve having operating Range from 100 PSI to 6000 PSI.

High pressure machines are provided with one valve and with high capacity priming pump for quick filling of system and fast response, having operating range upto 10, 000 PSI.

Pneumatics comparison testers can be use for vacuum to up to 350 PSI. This can also be used to check compound gauges.

Full set of adapters are standard accessories to enable to mount gauges with almost any connection size, right from 1/8" to 1/2" B.S.P. / N.P.T. and M20 x 1.5p. Pointer punch, required spanners and alen keys are part of tool kit so no other tools are required to operate or maintain the machine.

Salient Features:

Stainless Steel Construction allows use of water as a hydraulic media, which enables the use of hydraulic comparison tester in industries like Bulk Drugs, Calibration Gases, Oxygen etc. were hi standard of hygiene is required.

The Flame arrester protect storage, distribution and chemical process facilities containing Flammable gasses from fire and explosions. It is an effective device that isolate source of ignition and allows vapour to flow freely in venting and collection system. The most effective method of quenching flame is to install these. Flame arrester either at the strategic point along with pipe work system or at end of pipe line where gas/vapour are being vented into atmosphere.

These thermocouples are available in three types of hot junctions :

The Grounded Junction :Recommended for the measurement of static or flowing corrosive gas or liquid temperature and for high pressure application. The junctions are welded to the protective sheath giving faster response.

An Underground Junction :Used for measurement in corrosive application where it is desirable to have the thermocouple electronically isolated form and shielded by a seath. The junction is physically isolated from the sheath from MgO powder.

An Exposed Junction :It is used for the measurement of static or flowing non-corrosive gas temperature where fast response time is required. The junction extends beyond the protective seath to give accurate and fast response. The seath insulation is sealed where the junction extends to prevent penetration or moisture or gas which would cause.

Bimetallic Instruments are housed in Weatherproof IP 55 die cast Aluminium/S.S. 304 case or Pressed steel Non Weatherproof casing and are available in dial size of 25, 40, 50, 63, 100 and 150 mm. These instruments are available in rigid stem type bottom and back connection direct mountings. The hazardous environments generally warrants use of these type of instruments.
