Mineral Insulated RTD

Thermal Instrument is the leading Mineral Insulated RTDs Manufacturer in India providing reliable solutions for accurate pressure measurement to process industry worldwide.

Accurate temperature monitoring and control begins with a properly designed sensor. RTD – Resistance Temperature Detector used for temperature measurement (-) 200 C to 500 C (up to 800 C on request), must have the physical configuration necessary for optimum thermal response to the process fluid it is sensing and the resistive element compatible with instrumentation.

Routine tests:

a) Accuracy/Calibration Test
b) Nitrogen Leakage Test (Weld
Closure Conformity)
c) Insulation Resistance Test
d) Thermal Response Time Test
e) Continuity Test
f) Dimension Checks

Type tests:

a) Vibration test
b) Drop / Shock test
c) Self-heating error test
