The Senva P4-0010-DU1XX is a P4 Value Series dry-media differential pressure transmitter with a fixed 0 to 0.10 in WC range and a 4-20 mA (3-wire) output, accurate to ±1.00% of range. A MEMS silicon piezoresistive element senses dry, oil-free air or nitrogen for building pressure, filter status and duct static applications.

Key Features
MEMS Sensing Element
A precision-calibrated MEMS silicon piezoresistive element with microprocessor-based features. In Senva's own comparison against the capacitive, discrete-electronics Model 264, this is what makes the P4 compact enough for high-density DIN side mounting.
Non-Position Sensitive
Senva specifies the P4 as non-position sensitive, so it can be mounted flat, on edge or on its side without re-zeroing for orientation.
Push-Button and Remote Zero
Zero the sensor by holding the ZERO SET button for two seconds, or trigger it remotely through a dry-contact closure from the controller.
LED Status Indication
A single LED flashes every five seconds in normal operation, flashes rapidly above 110% of range, and pulses when zeroing completes - which also makes the sensor easy to locate in ductwork.
Flexible Mounting
Screw mount directly to duct, panel mount with self-tapping screws, or snap to DIN rail in either the back or left-side orientation to conserve panel space.
Conduit Ready
An optional conduit and terminal cover with a 3/4 in knockout lets the P4 land in conduit without a separate enclosure or adapter model.

Frequently Asked Questions
What pressure range does the Senva P4-0010-DU1XX measure?
P4-0010-DU1XX is a 0 to 0.10 in WC, unidirectional transmitter (approximately 24.9 Pa full scale by calculation). The range is set at the factory by the 0010 range code in the part number and is not field adjustable.
What output signal and supply voltage does P4-0010-DU1XX use?
It provides a 4-20 mA signal on a three-wire connection with a separate 12-30 VDC or 24 VAC supply, so the signal is independent of the power connection. Senva lists 4-20 mA loop powered, 4-20 mA 3-wire, 0-5 VDC and 0-10 VDC across the P4 Value Series, and the output is fixed by the part number rather than field selectable. Terminals are torqued to 3.5 in-lb.
How accurate is the Senva P4-0010-DU1XX?
±1.00% of range, which per Senva includes non-linearity, hysteresis and repeatability at 70 F. NIST-calibrated accuracy options are offered elsewhere in the P4 Value line if a documented calibration is required.
Does P4-0010-DU1XX include a duct probe?
No - the X in the last position of this part number specifies no probe. Senva offers the RP-6 remote/duct probe separately, and the same transmitter is also cataloged with the probe by changing that last character to P.
How do I zero the Senva P4-0010-DU1XX?
With power applied and no pressure on the ports, hold the ZERO SET button for two seconds; the LED pulses when zeroing completes. For best results, tie the high and low ports together while zeroing. Zeroing can also be triggered remotely through a dry-contact closure.
Is the Senva P4-0010-DU1XX Made in USA and Buy America compliant?
Yes. Senva manufactures the P4 series in Beaverton, Oregon, and lists P4 series dry pressure products on its Buy America / Buy American Act / BABAA / ARRA / TAA Commerce Declaration updated 04/21/2026, with domestic component cost exceeding 65 percent.
