  • Page 34: General Considerations

    6.5 General Considerations The PAS transmitter uses a piezoresistive pick up. As changes in pressure are accurately detected, any zero shift or installation offsets will be transmitted as a pressure change on the 4~20 mA analogue current output. Hence it is recommended that the transmitter be mounted as close to the process as possible and use short impulse piping, when possible, to achieve best accuracy.
