AMETEK 675压力变送器Description
The Model 675 is specifically designed for slurry and highly viscous applications where clogging of the sensor area is common. The Model 675 uses a 3.5” flush diaphragm to prevent unwanted clogging of the sensing area. This submersible level device is made of 316SS which offers outstanding environmental protection and is available in depths up to 138 feet of water.
The non-fouling flush diaphragm and cage assembly are designed to eliminate unwanted buildup of debris, fats, oils, greases, and other bio-solids by eliminating any potential gaps on the measurement area. The high integrity seal’s heavy construction eliminates the effects of turbulence on the sensor.AMETEK 675压力变送器
The 675 Series Transmitters indicate the level of liquid by continuously measuring hydrostatic pressure via its sensing element, an ion implanted silicon semiconductor chip with integral Wheatstone Bridge circuit. Once the sensor measures the pressure, the data is transmitted by a 4 to 20 mA output signal. This design provides for excellent reliability in remote and inaccessible locationss.
The Model 675 is approved for intrinsically safe operation in hazardous locationss as designated by Class I, Div 1, Groups A, B, C & D and Class II, Groups E, F & G. when used with an approved barrier.
All Model 675 transmitters are equipped with a sealed cable termination area and moisture absorbing desiccant canister. The purpose is to restrict moisture from entering the transmitter through the cable vent.
