AMETEK pressure transmitter Model 88
| Description Standard Version (Model 88C): A full-featured, all stainless steel transmitter, Model 88 is designed for years of stable performance in even the toughest environmental and media conditions. Approvals include FM and CSA for explosion-proof and CSA for intrinsic safety ratings. The Model 88 also meets NACE standards for offshore applications. A five year warranty is standard for the 88C. The small size and light weight of the Model 88 Transmitter eliminates the need for complicated mounting hardware and mechanical supports, thereby reducing installation time substantially. The integral junction box permits simple field wiring without the need for additional hardware, adding to the speed and ease of installation. An amplifier PCB enclosed in a sealed chamber is used to convert the millivolt signal from the sensor to a calibrated 4 to 20 mA transmitter output. Feedthroughs for EMI and RF protection are used between the amplifier board and the terminal housing. A 4 to 20 mA output is standard with a 12 to 40 VDC power supply. With all 316 stainless steel welded construction, the Model 88 is compatible with corrosive media and hazardous environments. With the cover retained by a stainless steel chain and no internal jumpers for span turndown, losses due to misplaced or dropped parts are eliminated. Flushmount Version (Model 88F): The Model 88F Pressure Transmitter is a durable, full featured, flush diaphragm pressure transmitter with all the features of the standard Model 88C. In addition, it is designed to mount flush against process media and to prevent any media particles, such as from paper slurry, from collecting at the diaphragm. Its rugged 316 stainless steel and HASTELLOY® C construction make it perfect for tough environments and corrosive media conditions. |
