Temperature transmitters
Head- and rail-mounted transmitters from Siemens, Endress+Hauser, ABB and INOR — configured, programmed and tested by us in our own laboratory.
A transmitter converts the sensor signal into a 4…20 mA signal. That pays off as soon as the cable gets longer or interference is involved: a thermoelectric voltage of a few millivolts picks up everything on its way to the control cabinet, a current signal does not. If the transmitter sits directly in the connection head, the interference-proof section starts at the sensor.
We supply the transmitters fitted and set to your measuring range — or separately as a replacement. The programming and a calibration certificate come from our own laboratory.
Mounting in the connection head
The most common design: the transmitter sits in the form B head and replaces the terminal block there.
HART · SIL 2/3 · Ex ia
SITRANS TH320
Siemens
Pt100, thermocouple, resistance, voltage · galvanically isolated
HART 7 · SIL 2 · ATEX
iTEMP TMT82
Endress+Hauser
one or two sensors · screw or push-in terminals
HART · ATEX, IECEx, FM
IPAQ-C330
INOR
universal input: RTD and thermocouple · galvanically isolated

IPAQ-C520
INOR
two sensors on one transmitter · redundancy or difference
4…20 mA
APAQ-C130
INOR
Pt100 and Ni100 · without galvanic isolation · the economical solution
4…20 mA
iTEMP TMT31
Endress+Hauser
Pt100 · without HART · measuring range set at the factory
Mounting on the DIN rail
For the control cabinet — when there is no space in the connection head or the transmitter has to stay accessible.

SITRANS TR320
Siemens
the same transmitter as the TH320, for the DIN rail
0.08 % · Bluetooth · ATEX
IPAQ-R330
INOR
universal input · 1,500 V AC isolated · operating hours counter
Which one fits?
| Your requirement | Matching transmitter |
|---|---|
| Only Pt100, no HART, price decides | APAQ-C130 or iTEMP TMT31 |
| Thermocouple and Pt100 on one type | IPAQ-C330, TTH300 or SITRANS TH320 |
| Safety-related measurement (SIL 2) | iTEMP TMT82, SITRANS TH320 or IPAQ-C520S |
| Zone 0 / Zone 1 | TTH300, SITRANS TH320 or iTEMP TMT82 in an Ex version |
| Two sensors at one measuring point | IPAQ-C520S (dual input) |
| Mounting in the control cabinet instead of the head | SITRANS TR320, IPAQ-R330 or IPAQ-R530 |
| Configuration without unscrewing the control cabinet | IPAQ-R330 (NFC and Bluetooth) |
