Schneider EPP301 Panel Differential Pressure Sensor 0-250Pa No Display
Product Overview
The SpaceLogic EPP301 is a premium, compact panel-mount differential pressure transmitter designed for high-accuracy tracking of air movement and HVAC filter status. With a dynamic measuring spectrum of 0 to 250 Pa, this display-less unit utilizes advanced piezoresistive micro-machined silicon technology to capture minute pressure differentials. Offering field-selectable 4-20mA, 0-5V, and 0-10V analog outputs, it features an on-board push-button auto-zero function that allows technicians to calibrate the device with a single click. The EPP301 is the go-to standard for commercial building mechanical panels and HVAC filter clogging diagnostics.
Technical Specifications

Power Supply / Voltage
Current output mode: 12 to 30 VDC
Voltage output mode: 24 VAC ±15% (50/60 Hz) or 15 to 30 VDC
Sensor Parameters & Accuracy
Measuring Range: 0 to 250 Pa. Supports sub-ranges: 0-50 Pa, 0-100 Pa, and 0-250 Pa, selectable on-board
Auto-Zero Calibration: Built-in front push-button for instant automatic zero-point drift correction
Regulatory & Certifications
UL 916, CE, RCM, FCC Class B, RoHS, WEEE, REACH
Enclosure & Material
IP65 / NEMA 4 fire-resistant enclosure. Complete with quick-release terminal block and dual brass barb fittings accepting 3/16" ID flexible tubing
Typical Applications
HVAC Filter Clogging Diagnostics
Panel-mounted within central control cabinets, with flexible silicone pressure tubes routed to the upstream and downstream of AHU air filters to detect clogging.
VAV Air Velocity Monitoring
Paired with in-duct pitot tubes or static pressure probes to translate velocity pressure into precise m/s measurements (0-15 m/s) for VAV box balance.
Fan Belt Failure Detection
Installed across HVAC centrifugal or axial supply/return fans to continuously monitor pressure drop, identifying fan belt slippage.
