Sensors & Switches

Pressure, temperature, proximity, photoelectric, and level switches and transducers for monitoring and control.

Anderson-Bolds carries pressure, temperature, and level switches and transducers from Barksdale, United Electric, Robertshaw, and Ronan, plus proximity and photoelectric sensors from Autonics and Carlo Gavazzi. We match the range, output (SPDT/4-20mA), and enclosure rating to the application.

Sensors & Switches — questions buyers ask

What is the difference between a pressure switch and a transducer?

A pressure switch trips a contact at a set point (on/off). A transducer outputs a continuous signal (e.g. 4-20 mA) proportional to pressure for a controller or PLC to read.
