Transmitter takes on hazardous duty

Stratford, Conn.— Ashcroft hazardous-duty process transmitters meet various standards for intrinsic safety. Sensors and signal conditioning circuits are interchangeable, making the transmitter upgradable and repairable by the user, which allows changeover on site. It offers 0.25% accuracy, male and female process connections, and a 4-20 mA output.

Stratford, Conn.— Ashcroft hazardous-duty process transmitters meet various standards for intrinsic safety. Sensors and signal conditioning circuits are interchangeable, making the transmitter upgradable and repairable by the user, which allows changeover on site. It offers 0.25% accuracy, male and female process connections, and a 4-20 mA output. Test points provide direct current measurement without breaking the loop. Electrical surge protection isstandard, and options include variable damping (0.1 to 3.0 sec), 3:1 continuous turndown, and user-adjustable zero elevation and suppression. Dresser Instrument Division
