Cable Sensor, Pt100/Pt1000 Sensors with 4-wire silicone cable for pockets or tubes 4-wire air sensors Elements in 1/1 DIN B, 1/3 DIN B and 1/6 DIN B The sensors can be used with the CombiTemp, Building Block Temperature Measuring System Description A platinum resistor is built into the temperature sensor. Changes in temperature are reflected by changes in the electrical resistance, so that measuring the value of the resistance gives an analogue expression for the actual temperature. The Pt100 element has a resistance of 100 Ohms at 0°C and a welldocumented working curve (DIN/EN/IEC 60751) within the nominal working range. The Pt100 sensor fits as an insert in sensor tubes with an internal diameter of 6 mm such as the CombiTemp temperature measuring system. Air sensors are used without sensor pockets to ensure fast response time. The sensors are used in a wide range of applications within the marine, industrial, energy and food sectors. www.baumerprocess.com Design and specifications subject to change without notice Data Sheet 2902-1 Page 1 Technical Data Standard sensor Common data for both types Measuring range -50...205°C Ambient temperature -50...205°C Case material Acid-proof, stainless steel AISI 316 Ti (W 1.4571) Marking label -30...105°C Case dimensions ø5.8 mm x 60 mm Pressure range < 25 bar (water flow 3m/sec.)
