Setra Model 270 Pressure Transducer Descriptions:
Setra Model 270 Pressure Transducer should be operated with the case connected either to the negative excitation terminal or to the negative output terminal. Failure to do this may result in damage to, or unsatisfactory operation of the unit. This connection may be made by connecting shield and black (negative excitation) leads or alternatively by connecting the shield and negative output signal leads together. Best shielding against noise will be obtained by connecting the shield and negative excitation leads. Circuit is reversed voltage protected for at least 5 minutes. Internal transient suppression network is provided for short duration transients to 150 volts.
