High precision pressure transmitter for measuring very low vented gauge reference or differential air pressures. Each presssure range can be adjusted to scale the 4-20mA or 0-10 volt output signal from 10 to 100% of the base range. Designed for measuring pressures across air filters, ventilation fans and valves on HVAC and pneumatic systems.
Pressure Ranges: from 10 mbar (4 inH2O) up to 300 mbar (120 inH2O) vented gauge or differential each with 10 to 1 digital turn down
Static Line Pressure (DP ranges only): 3 bar g max. for 10 and 100 mbar diff, 5 bar g max. for 300 mbar diff
Accuracy: ±0.1% FS (4-20mA), ±0.2% FS (0-10V) including +10 to +50 DegC
Output Signal: 4 to 20mA, 2wire or 0 to 10 volts, 3 wire
Electrical Connection: Binder 5 pole connector
Pressure Connection: G1/4 male positive side, 6mm dia tube with G1/4 adaptor for negatives side connection
Media Compatibility: Positive side - stainless steeel 316L pressure port, NBR/Viton O rings and gold coated ceramic diahragm. Negative side - dry non-corrosive gases
Special Features: high overpressure
Special Options: Digital ranging, ATEX IS certification II 1/2 G EEx ia IIC T4 for vented gauge reference ranges only
The 41-X high precision low range pressure transmitter utilises a capacitive ceramic sensing diaphragm which is specially developed for measuring low gas pressures with a high accuracy. Another benefit of the capacitive ceramic sensing technology is the high overpressure rating of 10 times for the 10 and 100 mbar and 5 times for the 300 mbar pressure ranges.
The analogue output signal can be adjusted by the user via the optional computer interface cable and configuration software. The 41 X high precision low pressure sensor uses a 16 bit resolution microprocessor to provide a high precision and dynamically responsive pressure reading.
