The Senva P5-0100-1LP is part of the Senva P5 Series Universal Dry Pressure Transmitter family - the multi-configuration unit in Senva's dry-pressure lineup. One SKU replaces multiple fixed-range transmitters in your stock: this unit's 0-1 in WC base scales to four selectable sub-ranges (settable via internal slide switch), with field-selectable output signal (4-20 mA 2-wire loop, 4-20 mA 3-wire, 0-5 VDC, or 0-10 VDC) and field-selectable direction (unidirectional or bidirectional). Built around a MEMS silicon piezoresistive sensor with non-position-sensitive design, manual or contact-closure auto-zero, and a patented enclosure with high-density DIN-rail mount and 3/8 in conduit-ready entry. This SKU ships with the optional LCD display for on-board pressure readout and the integrated duct probe with gasketed dampening tip for in-duct installation.

Universal = Inventory Reduction. The P5 is engineered to replace multiple fixed-range transmitters with a single stocking SKU. One technician visit, one part number on the truck - field-set the range, the output signal, and the direction to match the application. Eliminates call-backs caused by stocking the wrong range or output type, and reduces purchasing complexity for OEM and BAS contractors managing many sites.
Best for: low-pressure room and zone applications - building static pressure, clean room and isolation room differential, and laboratory exhaust hood proving. The universal output and selectable sub-range make this the right pick for OEM and BAS contractors who want one part number that fits many applications across their installed base.
7-YEAR
WARRANTY
Industry-leading 7-year limited warranty. Senva backs the P5 Series electronics for seven years - significantly longer than typical 2-5 year warranties on competing pressure transmitters. ZOT Supply is an authorized Senva distributor; product ships factory-new from Beaverton, Oregon with full manufacturer warranty intact.
Buy American Act (BAA) / BABAA / TAA / ARRA Compliant. The Senva P5 Series is manufactured in the USA with over 65% domestic component cost and qualifies under Buy American Act, Build America Buy America Act (BABAA), Trade Agreements Act (TAA), and American Recovery and Reinvestment Act (ARRA Section 1605) for federal, state, and municipal procurement contracts.

Key Features

Universal Output + Sub-Range

Four field-selectable output signals (4-20 mA 2-wire loop, 4-20 mA 3-wire, 0-5 VDC, 0-10 VDC) on a single internal switch. Four selectable sub-ranges on another switch. Field-selectable unidirectional or bidirectional via a third switch. One stocking SKU covers what would otherwise be 16+ fixed-range parts.

MEMS Silicon Piezoresistive Sensing

Solid-state silicon sensing element with precision factory calibration. Non-position-sensitive design - mount flat, vertical, or DIN-rail without zero shift. Thermal drift is 0.02% FSO per deg C (0.01% per deg F) referenced to 72 F. Accuracy is +/-1.00% of selected range typical.

0-1 in WC Base + Four Sub-Ranges

Base full-scale: 0-1 in WC. Selectable sub-ranges in unidirectional mode: 0.1, 0.25, 0.5, 1.0 in WC. Selectable bidirectional sub-ranges: +/-0.1, +/-0.25, +/-0.5, +/-1.0 in WC. Set via slide switches inside the enclosure - power off before changing.

Manual + Contact-Closure Auto-Zero

Front-panel pushbutton zero plus a separate remote-zero terminal that accepts a normally-open contact closure - useful for programmatic re-zeroing from the BAS. Press and hold ZERO SET for 2 seconds with no pressure applied (or with H and L ports tied together) to re-zero. Zero drift <0.004 in WC per year.

Patented DIN-Rail + Conduit-Ready Mount

Patented enclosure design with two DIN-rail orientations - back-mount for standard depth or side-mount for high-density panels. Integrated 3/8 in flex conduit cover with 3/4 in knockout means no separate fittings needed for typical commercial install.

LCD Display + Duct Probe Included

Ships with the on-board LCD for live pressure readout AND the integrated duct probe with gasketed dampening tip for stable in-duct measurements. The fully-loaded configuration - direct duct mount with on-board readout, no accessories to add.

Selectable Sub-Ranges & Outputs

This SKU is the 0-1 in WC base unit. All field-selectable options are set with slide switches inside the enclosure. Power must be off when changing switches.

Frequently Asked Questions

What sub-ranges and outputs does the P5-0100-1LP support?
This is the 0-1 in WC base unit. Inside the enclosure are slide switches that let you field-select the sub-range (4 unidirectional options: 0.1, 0.25, 0.5, 1.0 in WC, or 4 bidirectional options: +/-0.1, +/-0.25, +/-0.5, +/-1.0 in WC) and the output signal (4-20 mA 2-wire loop, 4-20 mA 3-wire, 0-5 VDC, or 0-10 VDC). Direction (uni or bi) is a separate switch. Power off the unit before changing any switch positions; new settings don't take effect until power is cycled.
How is the P5 different from the P4 Series?
The P5 is the Universal version of Senva's dry-pressure family. Where the P4 uses fixed ranges and fixed outputs (one SKU per range/output combination), the P5 lets you field-select the sub-range, the output signal, and the direction on a single unit. This means one P5 SKU can replace multiple P4 SKUs in inventory and on the truck. The trade-off: the P5 carries a +/-1.00% accuracy spec (vs the P4 Precision option at 0.25% or 0.50% NIST). Pick the P5 when inventory flexibility matters; pick a P4 Precision when documented NIST accuracy is required.
How do I wire the output signal?
Three terminals plus a remote-zero contact terminal. For 4-20 mA 2-wire loop: connect supply (12-30 VDC) and the 4-20 mA receiver in series through PWR and COM. For 4-20 mA 3-wire: PWR to supply +, COM to supply common, and the 4-20mA 3-Wire Out terminal to the receiver. For 0-5 VDC or 0-10 VDC: PWR, COM, and the 0-5/10V Out terminal. The Remote Zero terminal accepts a dry (N.O.) contact closure to trigger an auto-zero remotely. Tighten terminals to 3.5 in-lb. For 24 VAC supply, Senva recommends a dedicated isolation transformer since one side of the secondary ties to signal common.
What does the LCD display show?
The 5-digit LCD shows live differential pressure in the configured units. It's useful during commissioning, filter-loading testing, and balancing - verify what the transmitter is sensing without a separate manometer. The LED status indicator beside the display flashes every 5 seconds for normal operation, rapidly flashes when applied pressure exceeds 110% of the selected sub-range, and momentarily flashes when a zero operation completes.
What does the included duct probe do?
This SKU ships with an integrated gasketed duct probe that includes a dampening tip - the dampening reduces oscillation from turbulent airflow so the displayed reading stays stable in real duct conditions. The probe threads directly into the back of the enclosure for direct in-duct mounting. For applications where you need the probe in the duct but the transmitter mounted elsewhere, Senva also offers the RP-6 6-inch remote probe (sold separately).
How do I zero the transmitter and what media is it rated for?
The P5 is rated for dry, oil-free air or nitrogen (N2) only - not for wet, oily, corrosive, or particulate-laden media. To zero: with power applied and no differential pressure across the ports (or with the H and L ports temporarily tied together), press and hold the ZERO SET button for 2 seconds. The LED will flash momentarily when the operation completes. The unit also supports remote auto-zero via an N.O. contact-closure input wired to the Remote Zero terminal - useful for triggering periodic re-zero from the BAS to compensate for the long-term zero drift (typically under 0.004 in WC per year).
