Probe Insertion Length Rigid Rod - 50mm to 3, 000mm, Flexible Rope - 100mm to 20, 000mm

Operating Principle :

Earth Extension (body) Sensing Rod
The capacitance is formed by the sense rod and earth extension.
When no material is present, the capacitance is analogically a multiple of probe dimension and dielectric constant of air ε(air) ≈ 1.
When material is present, the capacitance gets multiplied by dielectric constant of the material.
This variation in capacitance is then translated into switching output by the device.

Features :

Fast Switching Response
High temperature endurable probes
Single sensor allows pump-control & multi-point switching
Easy calibration with or without material
Remote electronics with std 10 meters cable length
External indication LED available
Threaded & Flanged Mountings

Admittance Point Level Switch (LSY)

Min. Dielectric Constant 1.6 (non-hygroscopic)
Ambient Temp. -20 °C . 80 °C (-4 °F . 176 °F)
Process Temp. -20 °C . 100 °C (-4 °F . 212 °F)
Process Pressure absolute / max. 15 bar (with PTFE insulation), absolute / max. 2.5 bar (with Ceramic insulation)
Wetted Parts SS-304, SS 316, SS-316L, PTFE, part ceramic
Process Connection NPT / BSP 1", 1¼", 1½", 2" etc Flanged : ANSI/JIS/DIN/ASA/custom
Vibration Test As per IEC 60068 part 2-6 sinusoidal, 10-55Hz, 0.15mm
Probe Insertion Length: Rigid Rod - 50mm to 3, 000mm, Flexible Rope - 100mm to 20, 000mm

Operating Principle :

A Sine wave of high frequency is fed into both Sensing Rod as well as Compensation Shield.
Voltage at shield is equal to the voltage at sense, no effective current flows between sense and shield.
This removes shield-sense capacitance from the measurement.
Shield-earth capacitance is simply ignored by not measuring it.
This removes the effect of material coating on probe.
Material is detected by measuring sense-earth capacitance.

Rotating Paddle Point Level Switch (LSR)

Material SS 316 or SS 316L
Temperature -20°C . 80°C (-4°F . 176 °F)
Ambient -30°C . 100°C (-22°F . 212 °F)
Process Extensions & Heat Sinks Required
Pressure Atmospheric

Paddle guide pipe material SS 304, SS 316, SS 316L
Max length Blade Thickness 100mm to 2, 000mm 2mm

Operating Principle :

Trumen rotating paddle level switches are spring loaded eccentricaly driven rotating vanes or blades, which rotate at a slow roational speed of 3rpm maximum, using a geared motor.
When material is absent, rotating vanes are free to move and motor is held to its normal position by a spring.
When material level reaches the rotating vanes, it tries to stop the rotation. This causes motor move in reverse as the spring can no longer hold it in its normal position.
When motor rotates to a suffient degree, a limit switch gets triggered. This stops the power supply to the motor and another limit switch provides potential free output.

Features :

Rugged construction and design along with proper
sealing to prevent dust penetration.
No calibration required.
Extensible length model available
Different types of blades (vanes) available.
Stable and reliable performace

Applications : LSR is suitable for applications in free-flowing solid powders and grainules, for example in cement industries, plastics, pharmaceuticals, chemicals and fertilizers, powder, food and breweries, etc.
