Submersible Temperature Sensor

Category: Tags: ,

Description

The Ta993 submersible temperature sensor comes with a standard temperature range of 0 to +85°C with other calibrated ranges available on request.  It has a compact 25mm diameter and is designed for long-term and permanent submersion in liquids.

Installation couldn’t be easier as the temperature sensor is designed to be suspended by its cable within the liquid that it is measuring.  Plus, thanks to its stainless steel or bronze housing options and various cable material, the Ta993 submersible temperature sensor has excellent media compatibility.

The Ta993 submersible temperature sensor has an integrated amplifier to produce an industry-standard 4-20mA output scale.  What’s more, fast response time is guaranteed by the solid epoxy potting on the body which secures the resistance thermometer in place making sure that the sensor picks up temperature change accurately and quickly.

Rescaling the temperature sensor is easy using the optional ‘User Configuration Interface’.  You simply connect the output wires to the device, interface to the PC/Laptop USB port and use the free software supplied with the unit.
