Pressure indicator is incorrect pressure indicator is incorrect Cause 1: pressure transmitter power supply is normal. Solution: If less than 12VDC, whether there is a large load should check circuit, the input impedance of the load pressure transmitter should be consistent with RL≤ ( Pressure transmitter power supply voltage -12V) / (0.02A) Ω Reason 2: The pressure reference value is necessarily correct. Solution: If the reference low precision diaphragm pressure gauge transmitters retail, you need the other for high precision The pressure gauge. Reason 3: Consistent pressure indicating whether the pressure range of the instrument pressure transmitter range solutions: pressure indication and pressure range of the instrument must be consistent with the pressure transmitter range Reason 5: Pressure transmitter input impedance load should be consistent RL≤ (pressure transmitter power supply voltage -12V) / (0.02A) Ω Solution: If you do not comply, according to their different can take appropriate measures: such as increasing the supply voltage (but must be less than 36VDC), reduce load 6 other reasons: multi-point recorder did not record when the input is open; solution: If the open is: 1, can not be with other loads; 2, switch to other input impedance ≤250Ω recorder did not record the time. Cause 7: The corresponding device housing is grounded Solution: Device housing Grounding 8: Is the AC power and other power traces separate solutions: AC power supply and other power routed separately Reason 9: The pressure sensor is damaged septum pressure transmitter selection, serious damage can sometimes overload diaphragm. The solution: to be sent back to the manufacturer for repair. , BST6800-HP high static pressure transmitter is a high hydrostatic what? Two relatively large static pressure difference, such as △ P = PH-PL, PH and PL are static pressure, and the two great pressure, △ P will be small. Static: that is, not changing with time pressure diaphragm pressure transmitter, or slower change in pressure over time, which is not in the fluid flow rate on the table and the measured pressure values. BST6800-HP high static pressure transmitter differential pressure principle use of high hydrostatic pressure transmitter diaphragm principle, be used to measure liquid, gas or steam level, density and pressure, and then turn it into a 4-20mA DC current signal output. Also can communicate with each other with a HART Communicator, through their set, monitor and so on.
