The assemblies listed below are designed for a broad range of applications that require resistance to corrosion and chemical attack. They provide very good temperature measurement and service life in plating, pickeling, and acid bath applications. The stainless steel sheath is coated with FEP and includes a fused FEP tip for excellent corrosion resistance.
Heat-tracing Thermocouples are made for use in systems that measure the surface temperature of process pipe that is carrying products whose temperatures must be controlled to prevent freeze-up, or to maintain a viscosity level so that the inner medium will flow. These sensors are constructed with Thermocouple sensing elements inside 316SS sheaths, and with a 3/4" Radius stainless steel mounting pad. Cold legs are available in customer-specified lengths to accommodate pipe insulation thickness.
The averaging RTD sensor listed below measures the temperature over the entire sheath length to provide an average temperature measurement of the cross sectional area of air ducts, room gradient temperatures, and other low temperature averaging applications. The sensing element has a resistance output that conforms to a 100 Ω platinum element with a 0.003 85 ºC-1 temperature coefficient within a measurement range of (0 to 100) ºC (32 to 212) ºF. The RTD sensors are available in copper or 316 stainless steel sheath materials and can be supplied in various lengths up to 800 inches. All RTD sensors 48 inches and longer will be shipped in a coiled configuration. The sensors on this page can be provided with a (4 to 20) mA Transmitter integrally mounted inside the available enclosures.
The Pyromation thermostat temperature sensors are provided with the sensor, or the sensor and a (4 to 20) mA temperature transmitter, mounted on a sub plate within a standard size thermostat housing. The thermostat housing measures 2-3/4" h x 4-1/2" w x 1-5/8" d and can be mounted either horizontally or vertically on a 2" x 4" electrical hand box. The cover is vented on two sides to provide for airflow over the sensing element, regardless of mounting position. The standard temperature sensing elements are available as a fluoropolymer insulated thermocouple or a three-wire Resistance Temperature Detector (RTD). Matching transmitters are available for all configurations and output ranges.
The magnet sensors are designed to measure the surface temperature of ferrous metals with a convenient and non-destructive magnetic attachment. These sensors are designed to be mounted either vertically or horizontally and may be attached to molding press platens, bearing/motor housings and various other metal surfaces. The magnet sensors have a continuous operating temperature of 400 ºF. The T and H series can take intermittent temperatures up to 600 ºF, but the pull of the magnet will be degraded at temperatures above 450 ºF. The M series has a 2 lb. pull force magnet and the T and H series have a nominal 10 lb. pull force magnet.
The sensing elements listed on this page can be cut to any desired length over 3" long by using an ordinary tubing cutter. All sheaths are provided in 316 stainless steel.
