WaterTechw² D062 Temperature Sensor
The WaterTechw² D062 Sensor has been specifically designed to monitor temperature in wastewater and industrial effluent treatment applications. The result is a robust, accurate, easy to use and stable temperature measurement system. The sensors are filled with a special cast resin that protects against moisture. As standard, the sensors are fitted with 10 metre cable, but they can be supplied with other lengths on request.
The sensor within the probes consists of a metal cylinder containing the thermistor network. This sensor tip is fitted to a black plastic housing. The sensors are designed for use between -5ºC and +45º. The accuracy of the measurement is +/- 0.2ºC. The sensor requires very little maintenance, with no special tools or training required. The sensor has been factory calibrated so does not require further calibration, however a verification process is available to ensure that the system is reading accurately.
- Temperature measurement in wastewater applications provides an important back up to measurements such as pH, Dissolved Oxygen, Suspended Solids and Turbidity. In activated sludge, temperature can be related to the ability of the biological treatment system to cope with varying loads. In Final Effluent many discharge consents are waived when the temperature reaches a low level of around 4ºC and by using a verifiable temperature measurement device such as the WaterTechw² D062 the operator can avoid issues with regulators.
The WaterTechw² D062 is supplied in two parts, an IP68 transmitter and an IP65 interface unit to provide a connection to the 7300w² Monitor. A blind 4-20 mA output version of the sensor is also available.
