Foxboro 13a Dp Cell Manual
Foxboro d/p Cell Transmitters have been the standard of process (a) See Optional Capsule Materials (13A Series Only) for span limits of 13A4 (Monel capsule. The Foxboro® brand Models 15A, 13A, and 13HA pneumatic d/p Cell transmitters measure differential pressure. Download Manual Model. Regarding This Manual.

Most transmitter calibration done is a five point calibration.CalibrationDP Transmitters. That is, adjusting one has an effect on the other. Foxboro 13A d/p Cell Flow Transmitter Manual 1526 May 1963 12 Pages UsedAll the reading obtained will be the as found readings. Record and put down the following can easily be sourced from transmitter nameplate: A typical DP cell transmitter calibration diagram is shown below.
That is the potentiometer is of a type that once fully adjusted clockwise or counter clockwise the screw may continue to turn without further varying the resistance for either direction.Note that these screws each connect to a variable resistance potentiometer and can be turned indefinitely. In most calibration done, you will be doing either a bench shop calibration — A bench calibration is a procedure where the device is calibrated at a calibration bench using calibration devices to simulate the process, — or a field calibration where the actual process is used.To calibrate an instrument involves checking that the output of the given instrument corresponds to given inputs at several points throughout the calibration range of the instrument. Foxboro 13a-ms2 manual – Google DocsHow to Calibrate Smart Transmitters. The graph below illustrates the correlation between input and output values.
Readings are taken for both increasing and decreasing input values and the corresponding transmitter output values are recorded Step 5: Share to Twitter Share to Facebook. For your application, this could be modified slightly.You are now ready to calibrate the DP transmitter. For example if the pressure source is a hand pump, you can easily control the pressure applied to the DP cell.

Models 15A, 13A, and 13HA Pneumatic d/p Cell® TransmittersWhether foxoro are doing a bench calibration or a field calibration, the low port of the DP transmitter cell is vented to the atmosphere as shown in the connection diagram above and the high port of the DP transmitter connected to a pressure source e. Record the current reading in m Fosboro which will be your first data point.
Foxboro 13a Calibration
The potentiometer has a maximum of 20 turns between minimum and maximum resistance therefore turning the ZERO or SPAN screws clockwise or counter-clockwise for 20 turns will cause the potentiometer to be at either maximum or minimum.
