Photo-Sensitive Sensor and Light Level Transmitter PSR-1, PSR-1-T

Photo-Sensitive Sensor and Light Level Transmitter

 

The Model PSR-1 Photo-Sensitive Sensor may be used as an input to indicate the presence or absence of light at the sensor location by a change in resistance. The Model PSR1-T Transmitter is a PSR-1 coupled with a 4-20 mA transmitter is ideal for energy savings and cost savings in Building Automation System, BAS, applications. The sensor is designed to be mounted in the end of a weatherproof conduit box.
