Profile: W.E. Instrumentation Ltd. is a supplier of process instrumentation. We are an ISO 9001:2008 certified company. Our product line includes wireless, pressure, temperature, level, panels, and valves. Our model 6081-P transmitter is ideal for monitoring applications. Our Model 6081-P measures pH and ORP, and is compatible with most Rosemount analytical pH and ORP sensors. The transmitter has a rugged, cast aluminum weatherproof and corrosion resistant enclosure (NEMA 4X and IP65). The transmitter includes a two-line 16-character display with simple and intuitive menu screens. Our DVC2000 Series digital valve controller is simple to use, compact, and designed for easy mounting. It converts a 4−20 mA input signal into a pneumatic output signal, which feeds the control valve actuator. Instrument setup is performed with a push button and liquid crystal display (LCD) interface. This interface is protected from the environment within a sealed enclosure.
