815PT Smart Pressure Transmitter

Brand: Cameron

The 815PT Smart Pressure Transmitter is a rugged, compact, loop powered instrument that is ideally suited for hazardous locations and hostile environments where space is limited.

The 815PT offers many industry standard outputs to meet applications where low-cost, discrete and continuous monitoring is required or preferred.

This versatile instrument may be used to safely monitor and control many process applications, but is specifically designed for upstream, midstream, and downstream oil and gas applications. Its stainless-steel construction and three-year warranty dramatically reduces the total cost of ownership.

The 815PT is easily configured using HART 7 Communication Protocol and Modbus RTU Serial Communications; it is also very easy to set the zero and span set points with a magnet, as the zero and span magnetic targets are clearly identified on the casting.

The Cameron 815PT is a feature rich, low cost, stick form-factor transmitter that sits at the top of its class.
