M610 Series II DP Transmitter Assembly
Description The M610 Series II DP transmitter assembly is designed to accept a differential pressure input from a primary flow element such as an orifice plate or Gilflo flowmeter and convert it into an analogue 4 - 20 mA output signal. The standard version comes with digital communications in the form of HART ® 5.2 which is superimposed on the 4 - 20 mA output. The 3-way manifold which is supplied already assembled to the DP transmitter acts as a means of secondary isolation and as a pressure equalisation valve to check the zero of the DP transmitter. The M610 Series II DP transmitter assembly consists of two items: - A high accuracy (0.1%) differential pressure transmitter. - A 3-way carbon steel isolation manifold. Note : These items are supplied already assembled. Pipe connections The process ports on the 3-way manifold are threaded ½ " NPT at 54 mm centres. Electrical connections ½" NPT x 1.5 screwed terminals (M20 adaptor supplied). M610 Series II technical data
