AMETEK831发射器Description
The Model 831 transmitters are the most durable, accurate and cost effective fixed range pressure transmitter available. An all 316 stainless steel transmitter, it is designed for years of stable performance in even the toughest environmental and corrosive media conditions. With its all-welded construction, this transmitter is weatherproof and capable of a direct spray with forces up to 200 psi without internal leakage. The Model 831 (standard and low power) has FM and CSA explosion-proof ratings. The 831D (differential pressure) also carries the CSA explosion-proof rating. All Model 831s meet NACE standards for offshore applications. A one year warranty is standard with every unit.AMETEK831发射器
The small size and light weight of the Model 831 transmitter eliminates the need for complicated mounting hardware and mechanical supports, thereby substantially reducing installation time. The in-line connection permits simple field wiring without the need for additional hardware, adding to the speed and ease of installation.
The standard Model 831 and the Model 831D feature a 4 to 20 mA output standard with a 12 to 30 VDC power supply. The Model 831 Low Power provides a three wire 1-5 or 0.8-3.2 voltage output and requires less than 30 millwatts of total power to operate. The combination of low power requirement, small size, excellent performance and low price make the Model 831 Low Power Transmitter ideal for critical outdoor applications. This model requires 6 or 8-14 VDC excitation and is available in pressure ranges from 15 to 5000 psi.
