PendoTECH® Single Use Temperature SensorsTM measure temperature in your processes accurately and cost effectively. They are low cost for single use applications where elimination of cross-contamination is required yet robust enough and to be repeatedly cleaned and re-used. They are designed for in-line use and perfect for filtration and chromatography processes, filling operations, and general process monitoring. These sensors connect to monitors via a re-usable cable. Suitable monitors include the handheld unit TEMP-340, a PendoTECH Process Control System, or other pre-qualified third party monitors. Also, a stand-alone transmitter is available with a 4 to 20mA analog output. They are the alternative solution for use with tubing to the existing temperature measurements devices on the market.

Sensor Features

To optimally adapt to tubing the sensors are available with either a hose-barb fitting , a 1inch sanitary flange, or a luer fitting. The hose-barb and flange sensor designs imparts no obstruction on the fluid path that can cause a pressure drop. There is no dead-leg at the point where the temperature is measured. The luer fitting can be connected to a variety of fittings that can securely adapt to tubing or other devices. The temperature sensing element is a thermistor. No calibration is required because the temperature versus resistance for the thermistor element is well-defined within the specified accuracy range. Within the electrical instrument, the measured resistance is converted to the temperature. A disposable dip probe is also available to measure temperature within a vessel.

Connection to Monitors

The hose-barb and flange sensors and dip probe connect to the monitor via a 10ft (3.0m) long re-usable cable. One end has a molded connector to connect to the sensor connector and the other end has a 1/4inch headphone plug commonly used by many commercially available monitors. The luer sensor has a custom molded connector on the 7ft (2.1m) long re-usable monitor cable that is quickly secured to the temperature sensor. There is an alignment guide on the sensor that prevents it from being connected improperly. Disconnection of the cable connector from the sensors is quick and easy and the monitor indicates the sensor has been disconnected.
