Temperature Transmitters

Temperature transmitters cover every application within transmission of RTD and TC sensor signals into mA, mV, HART, PROFIBUS® PA and FOUNDATION™ Fieldbus communication.

'Smart' Head Mount temperature transmitters which accept most commonly used temperature sensors (also slide-wire sensors or mV inputs) and generates an industry standard transmission signal. Output range and other operating parameters are easily programmed using software running under 'Windows' without the need for re-calibration. Isolation is a standard feature to overcome any potential ground loop effects. Two microprocessors operate together to ensure error-free transmission across the isolation barrier. A sensor referencing facility enables the transmitter to be accurately matched to a particular sensor. ThermaCheck™ samples, validates and records critical temperature points at multiple locations or process accurately storing over 10,000 readings. ThermaCheck‘s management software allows efficient and effective corrective action within food processing, storage and preparation areas.

Mica Heaters

Mica Insulated Strip heaters / Plate heaters are sheathed in rust-resistance steel or in stainless steel sheath as it provides physical strength and good thermal conductivity. Specially selected mica grade and thickness is used to insulate the windings, providing excellent thermal conductivity and dielectric strength.

These heaters are available with various terminal options: Screw terminals / Pin socket or with flexible wire leads. Various mounting holes can be provided as per customer specifications.

Cartridge Heaters

High quality, high watt density cartridge heaters for plastics processing, packaging, hot melt dispensing, liquid heating, hot plates, and other and a variety of other applications. Swaged (compacted) cartridge heaters provide long service life at elevated temperatures with a wide range of termination options that can be adapted to most applications. We can assist you with proper specifications for a new application or help you solve a problem with your existing design.
