PA-21Y / 25BAR / 81554.33 / 4-20MA

The PA-21Y / 25BAR / 81554.33 / 4-20MA is a piezoresistive Pressure Transmitter for industrial applications. The Y-line transmitters have an extremely small temperature error. This is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1.5K wide. The TK zero and TK compensation values are calculated for each field and programmed into the additional circuit. During operation, these values are fed into the analogue signal path depending on the temperature. Each temperature is the Calibration Temperature for this transmitter. The accuracy there is mainly determined by linearity. The wider the temperature range, the greater the amount of testing that is needed to minimize the inaccuracy of the mathematical model.

• 4 to 20mA of Current
• Product Line is outstanding due to its extreme ruggedness towards electromagnetic fields
