Mineral insulated (MI) sub-assembly PT100 resistance thermometers provide a quick and low cost effective
way for sensor manufacturers to produce complete assemblies.
• The sensor manufacturer simply takes the part built RTD and fits it into a handle, pot seal, terminal head etc.
to complete the sensor eliminating the necessity for expensive welding equipment and workshop machinery.
• All part built MI RTDs are supplied in a 4-wire configuration in either Class A or Class B tolerance. The
operating temperature range is from -50°C to +500°C and the sheath material is 316 grade stainless steel.
• Termination is an epoxy seal (100°C) with 20mm of Nickel element tails for connection to extension wires.
• Each probe is calibrated and supplied with the Ω value at 0°C etched on the sheath along with the
manufacturing date and traceability code.
