ADPT-HALP High Accuracy Differential Air Pressure Transmitter W/LCD

Description

The HALP series is used to measure positive, negative or differential pressure. The piezoresistive sensor is ideal for monitoring the pressure of air or other clean inert gas. Typical HVAC applications include monitoring of filter differential pressure or VAV applications. An optional static pressure probe provides ease of installation for duct mounting. Several accessories are available. A hinged and gasketed polycarbonate enclosure is provided for ease of installation.

NOTE: Please specify input range required on any order (from datasheet).
Please contact us regarding 06 range (±40”, ±30”, ±10”, 0-40”, 0-30”, 0-10” WC) if required. Price is slightly different.
