Valve Positioners feature Hart® communication as standard.
Press Release Summary:
Constructed of aluminum or stainless steel, Series 185 and 285 Smart Positioners take 4-20 mA input signal to accurately control valve stroke of linear valves and rotary valves, respectively. LCD screen attached to outer surface of units allows inspection of positioner condition while in field. Housed in NEMA 4X enclosure with operating temperature of -22 to 185°F, positioners are available in single or double action models with auto calibration function.
Original Press Release:
NEW Series 185 & 285 Smart Positioners
W.E. Anderson Division of Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its NEW SERIES 185 & 285 SMART POSITIONERS.
The Series 185 Smart Positioner takes a 4 to 20 mA input signal to accurately control the valve stroke of linear valves. The Series 285 Smart Positioner also takes a 4 to 20 mA input signal to accurately control the valve stroke of rotary valves. Observations of the positioners condition are made easy with a standard LCD display. To help reduce operating costs, air consumption levels are near zero, without reducing the performance of the Smart Positioners. To ensure reliability, both the Series 185 & 285's construction consists of a durable aluminum or stainless steel. For added convenience, the auto calibration function ensures high accuracy of the unit. With HART® communication protocol as standard, both the Series 185 & 285 Smart Positioners factory settings can be configured as needed.
