Keller Series 35X Flush Diaphragm Pressure Transmitters

The Series 35X is a high-precision Piezoresistive pressure transmitter featuring a flush-mounted metal diaphragm and delivers a highly accurate, mathematically compensated output signal. Standard accuracy is 0.05% of full scale for both RS485 serial and analog outputs. The RS485 comms allow the Control Center Series 30 software, for easy reconfiguration of analog output ranges and adjustments to zero point and gain settings. With ATEX certification, the Series 35X is ideally suited for use in hazardous area applications.
