GTU/-2R-OMU - Details

Home --> Devices for Switch Panels / Industry --> Measuring Transducer --> Temperature Measuring Transducer


Temperature measuring transducer GTMU, completely with sensor (constructions with measuring transducer, electrically isolated, for outdoor applications as well as constructions without measuring transducer -  Greisinger electronic -


Temperature measuring probe

cpl. with Pt100 or NiCr-Ni (type K) sensor

 

General information:

At the GTMU you are able to select from 5 basic constructions and  2 sensor types. So you have got the possibility to adjust the system optimally to your requirements.
The constructions 1-4 are completely with sensor, measuring transducer incl, readily calibrated and so ready for mounting and use.
At construction 5 the sensor is missing, which you are already possessing or have to be ordered extra acc. to your wishes (please don't hesitate to contact us).
 

Design 1

to be screwed in directly

Probe with thread "G"

Standard: G= 1/2" (= 1,27 cm), FL= 100mm, D=6mm

 

Design 2

for higher temperatures

Thread  split from housing by collar tube HL

Standard: G= 1/2" (= 1,27 cm), HL= 50mm, FL= 100mm, D=6mm

Design 3

Room our outdoor probe

for direct wall mounting

Standard: FL= 50mm, D=3mm

 

 

Design 4

Channel probe


 

Probe mounted in the middle and vertical downwards

Standard: FL= 100mm, D=3mm

 

 

Design 5

for external probes

measuring transducer for already existing sensores Pt100 or NiCr-Ni
resp. also then, if probe and housing have to be mounted separately
(e.g. due to very high ambient temperatures or if necessary due to the construction
