Robust and reliable analog instruments that are directly mounted on the transformers with a +/- 4° accuracy. Models come with a maximum of 2 contacts and some models have inbuilt WTI scanners. These are small instruments with maximum dial size of 4” and are used mostly in smaller distribution transformers.
Instruments operate based on thermal expansion and contraction of helical Bimetallic coil.
Instruments need no external power supply required for indication or operation.
The sealed system requires no trimming or periodic site adjustments
Instruments are meant for Direct mounting on the Transformer & Other Process Control Equipment.
Instruments are available with the option of switches for control or plain indication.
