Pressure Transducer for differential pressure/ flow rate, with displa, 186,24 €

The pressure transmitter detects the overpressure, underpressure or differential pressure (P) between the two pressure inputs and converts the measured value into a linear output signal 0-10 V or 4-20 mA. 8 different scalings and the output damping of the pressure transmitter (0 sec / 1 sec / 5 sec / 10 sec) can be set on the device. Alternatively, the measuring device can be operated as a volume flow measuring device. It calculates the volume flow (Q) using the system-specific K factor (k) and outputs the calculated value as a linear output signal 0-10 V or 4-20 mA. The K-factor, the desired scaling for the volume flow output signal 0-10 V or 4-20 mA, the density of the medium and the desired volume unit (l or m³ per s / min / h) can be conveniently set via the display menu. The content of the backlit display can be rotated in 90 ° steps via the menu and the actual value, the set switching threshold, the relay status, the MIN / MAX measured values of the selected interval (1 h / 6 h / 12 h / 24 h) etc. can be read. For manual calibration of the zero point on site, the pressure transmitter carries out a zero point adjustment at the push of a button. If necessary, the pressure transmitter can be fine-calibrated on site using a SPAN controller.

Manual zero-point adjustment:	The zero point adjustment is started by pressing the button on the circuit board (push 10 s until LED stops flashing or by the display version the countdown 10-0 is completed). Before, a continuous operation of at least 1 hour must be sure, the offset must be in the middle position and the pressure inputs P+ and P- must be an obvious offense to the environment. The successful calibration will be signalized by 5 sec durable lightning of the LED.
