41X High Precision Low Range Pressure Transmitter

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.

Product Description

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.
