Specification

The digital amplifier Type 4620A... has been specially designed for use with piezoresistive sensors where a very accurate measurement is required. This versatile amplifier calculates actual pressure and temperature using digital compensation. Sensor specific coefficients are stored in an EEPROM in the amplifier. Various functions can be assigned to the digital input and output signals, e.g. error indication, limit levels, tare of pressure and temperature signals using an external trigger.
