The new MTE Efficiency pressure transmitter platform offers exceptional cost-effectiveness for precision applications. The modular platform allows individual adaptations in the shortest possible time and stands for high accuracy and stability. It comprises the MTE7000, MTE8000 and MTE9000 transmitter series.

The MTE7000 series is based on piezoresistive pressure sensors and is particularly suitable for measuring dry, non-corrosive gases from as low as 10 mbar. The MTE8000 series, which is based on piezoresistive ceramic pressure sensor elements, consists of pressure transmitters with stainless steel housings and has a particularly high media compatibility for corrosive liquids and gases. The same applies to the MTE9000 series, in whose stainless steel housing fully welded stainless steel pressure sensor elements without internal elastomer seals are used.

Thanks to new production processes and a more compact design, users benefit from particularly low costs for all three series.

LHD Ultra - two elements in one housing

The new LHD Ultra series comprises high-precision 2-in-1 differential pressure sensors that combine two sensor elements with different pressure ranges in a single housing. Based on thermal microflow measurement in combination with First Sensor's own key technology - the integration of the microflow channel and the thermal MEMS sensor element on an SI chip - they measure a pressure range from 0 to 5,000 Pa. They offer maximum precision even in the lowest pressure range around the zero point. The models have a 16-bit analog-to-digital converter for the upper and lower ranges. A special averaging process results in a 24-bit resolution for the entire working range.

The overall accuracy is 1.5 percent (typical) of the measured value over the entire range from one to 100 percent of full scale. The models are equipped with a linearized digital I2C or SPI output as well as an integrated on-chip temperature sensor and a barometric sensor. The sensors also impress with their compact dimensions and wide range of applications.
