Water Temperature Sensors Product Description

Global Water’s submersible temperature sensor is a rugged reliable water temperature measuring device. The temperature transmitter probe is molded to 25 ft of marine grade cable, with lengths up to 500 ft available upon request. The temperature sensor has a two wire configuration for minimum current draw. The temperature transmitter’s electronics are completely encapsulated in marine grade epoxy within a stainless steel housing (online version has ¾ x 6 inch PVC pipe nipple, threaded both ends with cap).

Global Water’s GL500 Temperature Recorder adds recording capabilities to the temperature transmitter.  The GL500 Temperature Recorder connects to the temperature sensor’s 4-20mA output to record data.  In addition, Global Water offers the PC320 Temperature Controller to use the temperature transmitter’s output to control pumps or alarms.
