Temperature sensors PT100 Temperature Sensor PT100 Temperature Sensors for use with Hydrotechnik Hand-Held and Panel Mounted instruments. Each sensor has a platinum (Pt) 100 Ohm resistor located inside a stainless probe. Accuracy is ±0.1 °C. Output is 4 - 20 mA. Connect to a PT sensor at up to 630 Bar. Contact is made with the fluid being measured. DS03 RPM Sensors are also used with Hydrotechnik Hand-Held or Panel Mounted instruments. The principle is a sine wave infra-red beam that is turned through 90 degrees by a reflective tape. The sensor is not prone to giving false readings due to other light sources. The DS03 works up to 1 metre away from the rotating part. 4 - 20 mA Temperature Part number -50 to 200 3969-04-01.00 RPM Part number 0 - 30,000 3130-02-01.00 This site and all photography and illustrations are the copyright of Flowtechnik, a division of Hydrotechnik UK Limited © 2004
