Air Sensors

PWF 203

APPLICATIONS

Air resistance sensors are for temperature measuring of gaseous mediums. The gauge slide is at the perforated part of the sensor tube. The passage of the leads to the protection tube is strain relieved. Ø 8 x 65 mm spring is used as anti-kink protection. Standard leads are galvanized copper wires insulated with PFA- and fiberglass insulation and covered by fiberglass and steel metal braid.

Clamping screws

Clamping screws are variable adjustable at the sensor tube. It is a save and sealed connection at process entry. An advantages of the clamping screws is the easy assembly and disassembly of the Temperature Sensor. Various designs in various materials and threads for different diameters are available.
