CRA-310 - differential pressure transmitter (gases, vapours and liquids)

The CRA-310 transmitter is applicable to the measurement of differential pressure of gases, vapours and liquids. The active element is a piezoressistant silicon sensor separated from the medium by separating diaphragm and a specially selected type of manometric fluid. The electronics is placed in a casing with a degree of protection IP 54.

The electrical connection is a DIN 43650 connector. Potentiometers can be used to shift the zero position and the range by up to 10%, without altering the settings. The transmitter is not heavy, so it can be installed directly onto impulse lines. For fitting in any desired position on a Ø25 pipe the mounting bracket is recommended. The version with C type process connection can be fitted directly to a 3- or 5-valve manifold. The factory-mounted transmitters with VM type valve manifold are recommended. A transmitter without a valve manifold can be fitted in any position on a 2" pipe or on a wall using the C-2" mounting bracket. When the special process connections are required for the measurement of levels and pressures (e.g. at food and chemical industries), the transmitter is provided with a diaphragm seal.
