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.

D33 Differential Pressure Transmitter – D-Series
HART Communication, stainless steel enclosure suite for all applicationsD33 Differential Pressure Transmitter – D-Series
The D33 SMART Differential Pressure Transmitters are suitable for measuring differential pressure of gases, vapours and liquids. The active sensing element is a piezoresistive silicon sensor separated from the medium by a diaphragm and by a specifically selected type of manometric liquid. The casing is made of cast aluminium alloy or 316 stainless steel with IP66/67 protection. The design of the casing enables the rotation of the casing by 0-355° relative to the sensor, and a choice of cable direction. The model D33 Differential Pressure Transmitter is suitable for measuring pressures from -100mbar to 70bar with maximum working pressures up to 420bar.
Key Features
- Accuracy +-0.1%
- 4-20mA output signal
- Fully HART ® compatible
- Static pressure limit up to 420 bar
- ATEX certified (Intrinsically Safe)
- Gold plated diaphragm option
- Hastelloy C276 wetted parts option
