Cox Instruments Series PA-115, Turbine Meter Preamplifier Explosion-proof Housing 20 V p-p Pulse, Two-wire System (power supplied over signal wires)

COX Series PA-115 Turbine Meter Preamplifiers are used for long distance signal transmission and noise interference elimination. Their output signal frequency is proportional to the process flow rate. Meter- or remote-mounted units are available. The Series PA115 is intrinsically safe and available with either Factory Mutual or CSA approvals. An optional flow meter mounting kit allows for swivel adjustment to align to conduit. Remote meter mounting is available.
