Ultrasonic Level Switches

Ultrasonic Liquid Level Switches

- Designed for high or low level alarm duties to give a voltage-free

  contact or solid state transistor output for alarm signalling or as

  part of a pump control system.

- Manufactured in Polyphenylene Sulphide (PPS) for corrosion

  resistance in most liquids

- Top, bottom, or side-installation flexibility in tanks

- Small, light, robust and easy to install

- No moving parts


Ultrasonic Point Level Switches & Controller

- Used in non-hazardous area industrial processes to detect high or low liquid levels or liquid interface. The   level switches are fitted with dual-coaxial cable for connection to a Mobrey MCU200 Series Control Unit

- Choice of level switch designs for use in tanks and pipelines

- Industrial control unit option with alarm and fault output relays

- Operating Temperature : -94 to 302 °F (-70 to 150 °C) for 402SD and 442SD.

                                      -40 to 158 °F (-40 to 70 °C) for 433SD.

- Operating Pressure : Up to 1523 psi (105 bar)

- Compatible Devices : Mobrey MCU200 Industrial Controller


Dry Products Level Switches

PLS Rotating Paddle Switch

- Used as either a high or low level limit switch. It is easily

  mounted through a vessel wall. A small electric motor drives a   

  paddle which rotates freely in the absence of material

- Process Wetted Material : 304 stainless steel

- Housing Material : Aluminium alloy, powder paint coated

- Process Connection : 1.25-in. NPT or

                                  1.5-in. BSP thread for tank mounting

- Variety of paddle types available as accessories for light, medium,

  and heavy materials

- Can be used with granular, pelletized, and powdered dry products  

- They may be used in high level applications with materials

  over 160 kg/m3 and low or intermediate applications with

  materials over 80 kg/m3


VLS Vibrating Rod Switch

- The perfect solution for single point level switching in free flowing   solids across a wide density range, from fine powders to grains. A   single rod design provides the solution to tuning forks which may   become blocked or bridged

- Process Wetted Material : 316 stainless steel

- Housing Material : Aluminium alloy, powder paint coated

- Operating Temperature : -20 °C to +110 °C (Standard models)                                      -20 °C to +160 °C (High temperature models

- Operating Pressure : 10 bar maximum

- The vibrating rod level switch is the perfect solution for single point

  level switching in free flowing solids across a wide density range,

  from fine powders to grains. A single rod design provides the solution   to tuning forks which may become blocked or bridged.
