Temperature sensing, specified to the thermowell as well as the sensor.
Temperature is the most-measured process variable, and it is easy to get the installation wrong: wrong thermowell length, wrong sheath material, wrong accuracy class for the duty. We supply RTD and thermocouple sensors specified to the actual duty.
The sensor and the thermowell, picked together.
Most temperature problems trace back to the thermowell. A thermowell that is too short reads the pipe wall, not the process. A thermowell that is too long vibrates and fatigue-cracks. The sensor inside it is rarely the problem.
We size the thermowell to the line, the medium, and the flow velocity. The sensor is matched to the temperature range, accuracy requirement, and connection type. The transmitter is integrated where the loop needs HART or head-mount; rail-mount where the control panel handles it instead.
Four families.
- 01
RTD (Pt100, Pt1000)
Process temperatures from -50 to 500°C; the workhorse
Highest accuracy in standard duty; 3-wire or 4-wire connections
- 02
Thermocouple (K, J, T, N)
Higher temperatures (up to 1200°C+), faster response
K-type most common; T-type for cryogenic; N-type for stability
- 03
Sanitary RTD
CIP / SIP loops, F&B process temperature, dairy
Tri-clamp connections, hygienic body design, FDA-grade materials
- 04
Surface / clamp-on
Non-invasive pipe temperature; quick spot-check
Strap-on or magnetic; used for surveys and retrofit measurement
