Dwyer Series GS Gap Switch |
| Liquid
Level Measurement, 1000:1 Wet/Dry Ratio, 316 SS Wetted Parts |
|  Series
GS Gap Switch measures liquid levels at a single point and
provides a 10A relay output for high or low level alarm, overflow
prevention, and pump protection. The Series GS uses ultrasonic
wave propagation between the transducer gap to sense the presence
or absence of a liquid. Integral electronics make installation
quick and easy. Units can be mounted in either a vertical
or horizontal position with no additional calibration required.
Gap switch includes a 0.5 second delay and high level failsafe.
