Ashcroft CX8MB2422IWL Pressure Transmitter

The Ashcroft CX8MB2422IWL differential pressure transmitter is a low‑range sensor in the CXLdp family designed for HVAC and air‑handling applications, providing a differential pressure range of -2 to 2 inches of water (inH2O) and converting it to a 4–20 mA output powered from 12 to 36 VDC. It delivers accuracy of ±0.8% of full scale with a fast ~250 ms response time, making it suitable for monitoring duct pressure, filter status, and air flow changes in real‑time. The device uses a 1/4" barbed male process connection for straightforward installation and supports mounting on a DIN rail or standard panel, aligning with common control‑cabinet configurations. It is intended for air and non‑corrosive gases, and wiring is typically accomplished via a terminal block for reliable electrical connections. For resilience in HVAC environments, it tolerates modest pressure spikes with a proof pressure of 10 psid and a burst pressure of 25 psid, while operating across a temperature range of 0° to 160°F (−18° to 71°C). This model sits within Ashcroft’s CXLdp differential pressure line, emphasizing stable capacitive sensing and precise low‑pressure measurements, making it a practical choice for continuous monitoring of room pressurization, fan performance, and filtration integrity in commercial and industrial settings.
