Maltec-T MT8000-2R RTD Multipoint Sensor – Contacting Fixture Design

The Maltec-T MT8000-2R Multipoint Sensor is tough and lasts a long time. It usually comes as a 4-wire RTD and can measure up to 12 points. the Maltec-T MT8000-2R is used when a high local resolution is not required. You can get it with or without thermowells.

If your equipment needs an RTD signal, this sensor is the best solution. But if you’re using transmitters and need more measurement points or a wider temperature range, you might want to consider a thermocouple sensor like the Maltec-T MT8000F.


The Maltec-T MT8000-2R offers two different element fixation methods:

1) Radial spring design
This design provides very good thermal contact between the RTD and the thermowell, making it respond quickly. A spring presses the RTD against the inside of the thermowell. If you order it without a thermowell, it will shipped as a coil. The individual RTD elements cannot be replaced.

2) Spacer design
This design uses spacer disks to place the resistance elements correctly. You can’t replace the individual RTD elements and for shipping, the spacer design can’t be coiled up, with or without a thermowell.
