Temperature transmitter application

Temperature transmitter with standard 4 to 20mA, 0 to 10V output signals and with the HART or PROFIBUS communication protocols can be mounted in the connection head. Transmitter installation is carried out directly on the measuring insert (in place of a terminal block) or in the high cover connection head (solution used to enable installation of two transmitters).

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 to 20mA. This version makes the local temperature reading and transmission of the analogue signal possible.

 


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

  Range of application (°C) Formula for calculating acceptable deviations (°C)
AA -50 to +250 T = ±(0,10 + 0,0017 |t|)
A -100 to +450 T = ±(0,15 + 0,002 |t|)
B -196 to +600 T = ±(0,3 + 0,005 |t|)

|t|- absolute value of temperature.
