Description
The Chell microDAQ-PCU (Pressure Calibrate Unit) is a useful addition to the Chell pressure scanner line. The microDAQ-PCU will connect to a number pressure scanners and a pressure controller. It will take control of the scanners and calibrators and manage the (usually annual) calibration process in seconds.
The microDAQ-PCU is first configured with up to 6 pressure controller and 32 pressure scanners. The user can then assign one pressure controller and any number of pressure scanners to a CRG (Calibration Range Group). The user can then perform the following actions on that range group.
- Re-zero the scanners
- Calibrate the span of the scanners at nominated pressure
- Perform a 5 point pressure validation
- Output the results of all processes in a text file format
- Save new coefficients for future use
The microDAQ-PCU features an internal web browser interface or a command line interface so it can be operated from customer’s software.
The web server features and easy to use graphical interface and keeps the user informed of the calibration pressure, the output of the scanners (CH1), the valve position of the scanners and if the scanner passes a pre- configured performance target.
The microDAQ-PCU is a single board PC which is PoE powered and can be placed anywhere in the calibration network.
The microDAQ-PCU can also be used to calibrate legacy analogue scanners that benefit from frequent on-line calibrations. These can be interfaced with the microDAQ2, CANdaq5 and micro QD-VP products.
