Rotating Paddle Level Switch – PLS Series
Full option of available paddles, ATEX approvedRotating Paddle Level Switch – PLS Series
The paddle switch may be used as either a high or low level limit switch. It is easily mounted from above, or through a vessel wall. A small electric motor drives a paddle which rotates freely in the absence of material. When the paddle is impeded by the presence of material, a microswitch actuates an alarm signal. As soon as the paddle is completely stopped from rotating, power to the motor is cut, thereby extending motor life. After the material level falls, the motor is returned to its normal position and the paddle begins to rotate again.
Failsafe models use a microcontroller for self-validating diagnostics and monitor both motor and shaft rotation to detect and indicate a fault condition on the fault relay.
The PLS Series of switches 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.
Key Features
- Failsafe option
- High temperature option
- 1½” BSP or 1¼” NPT threaded connection
- Side or top mounting
- Shaft or cable extensions
- Robust aluminium housing
- IP66 ingress protection
- AC or DC supply voltages

Vibrating Fork Level Switch for Solids and Liquids – DMS & DMT
Stainless steel sensorVibrating Fork Level Switch for Solids and Liquids – DMS & DMT
The Vibrating Fork Level Switch (DMS & DMT series) is the perfect completion of Delta Mobrey’s range of level detection solutions. This instrument completes the range of products for the control of level in tank, silos and pump protection. Solid products like grains or aggregate can be controlled with the Vibrating Rod (VLS), and the application can be expanded to granules and powders with the Vibrating Fork series.
The same is also available for the controls of liquids, in combination with the Ultrasonic series 003 and all the mechanical float types.
The vibrating forks are energized and kept in resonance by an electronic circuit. When covered by material, the damping of the vibration is detected by the electronics, which switch the output relay after a configurable time delay. The vibrating fork level switch is the perfect solution for single point level switching in free flowing solids and liquids across a wide density range, covering all the needs from industrial applications to the compactness requirements typical of the applications on machines.
Key Features
- Configurable action
- Threaded or flanged connection
