bmTR01 Piezoresistive Pressure Transmitter

This piezoresistive pressure transmitter has an extremely small temperature error and this is achieved by dividing the temperature range into 120 fields that are 1,5 Kelvin (K) wide for a total temperature range of 180 K. The TK zero and TK compensation values are calculated for each field and fed into the analogue signal path depending on the temperature. Each temperature is the “calibration temperature” of this transmitter. The accuracy is mainly determined by linearity.

The product line is outstanding due to its extreme ruggedness towards electromagnetic fields. The limits of the CE standard are undercut by a factor of up to 10 with conducted and radiated fields. These transmitters are also extremely immune to external voltages between the housing and the electrical connection, which is particularly important when frequency converters are being used. The high insulation voltage of 300 V make this product ideal for use in the harshest of environments
