Typical applications include the measurement of blast pressure, chimney draughts or pressure / underpressure in furnace chambers. The ability to select the radical conversion characteristics enables the transmitter to be used in gas-flow measurement systems using reducing pipes or other impeding elements. The transmitter can withstand overpressure up to 1 bar. The housing of the electronic circuit has the degree of protection IP66/IP67. Communication with the transmitter is carried out with a KAP-03 communicator, some other Hart communicators or a PC with an Hart/USB converter and RAPORT 2 configuration software. Configuration, calibration The economical version can be mounted on any stable construction using the mounting bracket. The transmitter’s connection shanks have terminals to be connected to the elastic Æ6×1 impulse line. Where the pulse comes through a metal pipe, we suggest an M20×1.5 adapter for a Æ6×1 fitting using. The following metrological parameters can be configured: ¨ The units of pressure, ¨ Start and end-points of measuring range, damping time constant, ¨ Conversion characteristic (radical, inversion, user’s nonlinear characteristic). Ability to calibrate the transmitter with reference to a standard pressure. APR-2000ALW/G Economic Version, process connection with terminal connecting to Æ6 pipe (PCV type) Additionally, the data interchange with the transmitter enables the users to identify the transmitter, read the currently measured pressure difference value, output current and percentage of measuring range. The transmitter with a C type connector should be mounted on a 3- or 5-valve manifold. We recommend use VM type

Operating guidelines The transmitter should be mounted in a vertical position. The impulse lines should be connected in such a way that any condensed liquids flew off away from the device. Where there is a significant difference in height between the place where the transmitter is mounted and the place where the pulse is taken, the measurement may vary with the temperature of the impulse line. Connecting a compensating pipe close to the impulse line, from the transmitter's reference connection shank to the height at which the impulse is taken can minimise this effect. To prevent dust from...
