Aci 144807 Relative Humidity with Temperature Transmitter 20 feet Probe

Product Description

The ACI 144807 is a relative humidity transmitter with temperature output, featuring a remote 20-foot plenum-rated probe and a NEMA 4X enclosure. It provides selectable humidity outputs (0-5 VDC, 0-10 VDC and 4-20 mA default) and a 4-20 mA temperature output when used with the included 1,000 ohm RTD. The sensor uses a thermoset polymer capacitive element with a hydrophobic filter and conformally coated electronics for moisture resistance.

• Selectable RH outputs: 0-5 VDC, 0-10 VDC and 4-20 mA; temperature output 4-20 mA with 1,000 ohm RTD
• Remote plenum-rated 20 ft probe, NEMA 4X (IP66) enclosure, ±1% measurement accuracy with NIST certificate
• Thermoset polymer capacitive sensing element with hydrophobic sintered filter, conformally coated circuit board, DIP-switch single-point calibration

Product Highlights

Remote 20 ft plenum probe; multi-output humidity (0-5 V, 0-10 V, 4-20 mA); NEMA 4X enclosure; ±1% NIST accuracy
