Mineral Insulated Thermocouple Sensor


Temperature transmitter application

Temperature transmitter with standard 4÷20mA, 0÷10V output signals and with standard communication protocols can be mounted in the connection head, in place of a terminal block, or in the control cabinet.

Local display application

The temperature sensor can be equipped with the connection head enabling the local LED display installation. The local display operates in current loop 4÷20mA. This version makes the local temperature reading and transmission of the analogue signal possible.

Non-standard design

Immersion length and other parameters can be customized per client request

 


Compensation / thermocouple wire insulations
Insulation material Operating temp. range (°C) Properties
PCW (PCV) -10 to +105 Applied in mild environmental conditions.
Waterproof and flexible.
Yc- polyvinyl chloride -10 to +105 Applied in mild environmental conditions.
Waterproof and flexible.
FEP-teflon -50 to +200 Resistant to oils, acids and other aggressive liquids.
Si-silicone -50 to +180 Waterproof, flexible. Applied in high humidity.
Ws-fiberglass -60 to +400 Good resistance to high temperatures.Low resistance to liquid penetration.
Notes:Additionally, copper or steel braids/shields are used on wires to prevent electrical noises, Increasing, at the
same time, wire insulation resistance to mechanical damages. In case of longer wire lengths grounding may be
needed to minimize the noise in measurement circuit
