Kistler Universal Piezoresistive Amplifier Type 4657A
Kistler Universal Piezoresistive Amplifier Type 4657A on Euro-Card for piezoresistive sensors with current or voltage excitation and for 2-wire transmitters 4-20 mA.
Simple calibration of the measuring chain thanks to a built-in calibrating voltage source. An additional signal output allows to display the pressure value directly without numerical conversion. Potentiometers for adjusting the gain and zero measurand output on the front panel.
Power supply ±15 VDC. Connection with 64-pole terminal according to DIN 41612, form C.
