THE REFRIGERATION HOUSE DWYER TEMPERTURE TRANSMITTER MODEL NO 607.
The Dwyer Series 607 Differential Pressure Transmitter converts positive, negative (vacuum) or differential pressures of clean, dry air or other nonconductive, non-corrosive gases into a standard two wire, 4-20 mA output signal. Several factory calibrated models are available with ranges from 0-.10˝ w.c. to 0- 25˝ w.c. All models employ a variable capacitance transducer with a micromachined, ultra thin silicon diaphragm enabling precision measurement and control of very low pressures. Because no epoxies or other organics are used to seal the sensor, performance is exceptionally stable and drift free. It is also highly resistant to overpressure, shock and vibration. See specifications for complete details.

THE REFRIGERATION HOUSE Carbon monoxide MODEL NO: CMT200 Series CMT200 Carbon Monoxide Transmitter provides a field selectable current or voltage output that is proportional to the gas concentration in underground parking garages, vehicle maintenance facilities, or mechanical rooms. A field replaceable, electrochemical sensor provides accurate readings for up to 4 years with proper calibration. Field calibration can be done by using Model GCK-200CO-2000CO2 calibration gas, Model A-507A calibration adapter, and the on board span and zero potentiometers.
