Housing temperature transmitter 4-20 mA

The Testo Sensor housing transmitter is suitable for universal connection of resistance sensors and thermocouples. Resistance-based temperature probes (Pt100 / Pt1000 ) in two-, three- and four-wire technology as well as thermocouples can be connected. The transmitter provides an output signal of 4 to 20 mA. It is the ideal link between the temperature probe and your control system. Thanks to the innovative plastic housing with a tool-free rotary cover lock and the good use of space inside the transmitter, installation is quick and easy. Whether for a retrofit or new installation, our housing transmitter is optimally designed for use in plant and machine construction and features high accuracy, reliability, long-term stability and its robust product design.

Influence of the sensor cable
RTD and resistance (2-wire)					In two-wire circuits, the inherent resistance of the connecting lead adds to the resistance value of the measuring resistor (thermistor or Pt) and thus falsifies the measurement result. For this reason, we recommend the two-wire technique in conjunction with small-resistance measuring resistors only if you can use comparatively short connecting leads, i.e. small-resistance connecting leads.

RTD and resistance (4-wire)					Negligible

Housing transmitter - Mounting
Thanks to the four slotted holes, the housing can be easily mounted to the wall. The openings for the screws are located outside the protective space for the electronics, so there is no need for sealing. With the cable compression glands, sealing to the probe or data cable is guaranteed even for different diameters. Mounting material for the installation of the transmitter (screws and dowels) are included with the transmitter as free accessories. A large assortment of temperature probes and connecting cables is also available as an option. Important: To prevent measuring errors, the connecting screws for fastening the connecting cable must be firmly tightened.
Open the rotary cover.
Connect the required measuring element to the input according to the assignment plan. (Suitable measuring element NOT included in the scope of delivery, can be found in our store.) You can then parameterize input and output via the DIP switches.
Please lay cables with reserve loop and in such a way that no water can penetrate into the sensor head. This allows you to extend the probe without disconnecting the electrical connection.
