Design and function 4 3. Our sensors are available in single or duplex thermocouples configurations and 2 3 or 4 wire rtd s. 100 240 vac 24 vdc current. Commercial thermocouples are inexpensive interchangeable.

Our industrial sensors can be supplied with thermowell pockets in fabricated or solid bar stock construction and we also offer the option of direct mounted transmitters. An rtd is a metallic element whose resistance varies with temperature. There are three basic types of rtds. Field adjustable rtd s recommended for application up to 500 f 260 c.

Both with options of having in head transmitters. A thin film bulb calibrated to astm standard to class b or class a accuracy with a temperature coefficient of 0 00385 offers both excellent resistance to vibration and fast response. A thermocouple is an electrical device consisting of two dissimilar electrical conductors forming an electrical junction a thermocouple produces a temperature dependent voltage as a result of the thermoelectric effect and this voltage can be interpreted to measure temperature thermocouples are a widely used type of temperature sensor.
