Hello dear friend
I have installed Honeywell STD924 differential pressure transmitter instead of damaged ABB 266MST, but without air pressure inlet the display show -67%! I use a digital multimeter as ammeter. It measure 3,81mA.(i use 02 Test terminals on STD924).
When i connect the process pipe at high pressure side of transmitter it indicate -55%.
I look at other fine process line that use fine ABB 266MST transmitter. The process value show 24%. When dismantling the measuring pipe from high side of ABB transmitter, the ABB transmitter show -11%. How to calibrate the Honeywell transmitter std924 comparing to ABB MST 266. The transmitter is connected as analog signal input to JUCO PID regulator.
ABB 266MST has LRL/URL: -10/10mbar
span limits: 0.5mbar
the sensor: 0.5 to 10 mbar
on the body of ABB sensor is written: 0 to 25.000 MMH20
STD924 SPAN LIMITS: 25mbar
other question: the Honeywel STD924 isn't write protected? as information, i don't have the HART TRANSMITTER FOR CALIBRATION AND ADJUSTMENT.
Best regards
