LKM 753/4
The LKM753 is a radio transmitter for sensors like Pt100, Pt1000 various thermocouples as well as sensors with I²C bus. For the latter, the TMP116 and the SHT31 have been integrated so far.
have been integrated. The sensors are not included in the scope of delivery of the radio transmitter, but can be obtained from us on request. All transmitters are supplied as standard with a cable gland for connecting the sensor. On request, sensors can also be screwed directly.
So far, four different housing variants are available for the LKM753 radio transmitter.
The housing variant LKM753/4 offered here includes the standard A-head with a process connection M24 x 1.5.
