SENVA P6 Pro Series Pressure

Product Information

P6 Universal Pressure Sensor

The P6 Universal Pressure Sensor is a device that helps measure pressure levels in air or nitrogen. It comes in three models (0-5/15/40 W.C.) with four selectable ranges. The device has a screw mount and can be directly mounted on a duct or panel using self-tapping screws. The output selection switch allows for choosing the appropriate analog output (4-20mA 2-Wire or 3-Wire configurations or 5V/10V). The rotary range selection dial helps to select the desired pressure range position. The device also comes with configuration switches to adjust the device settings. The sensor hose barbs accept 1/8 & 1/4 ID tubing and have high (+) and low (-) ports labeled on the sensor. The device can be wired for voltage or current output as shown in the wiring diagrams.

It is important to note that Senva products are not designed to be used as the lone device for life or safety applications. Senva products are not intended for use in critical applications such as nuclear facilities, human implantable device or life support.

Product Usage Instructions

1. Mount the sensor directly to the duct or panel using self-tapping screws.
2. Move the output selection switch to select the appropriate analog output.
3. Move the rotary range selection dial to the desired pressure range position.
4. Use the configuration switches to adjust the device settings.
5. Plumb air lines to sensor hose barbs (accepts 1/8 & 1/4 ID tubing). High (+) and low (-) ports are labeled on the sensor.
6. Wire the sensor for voltage or current output as shown in the wiring diagrams.
7. Apply power to the sensor. With no pressure applied, press the ZERO SET button for 2 seconds. (For best results, temporarily connect high and low pressure ports together while zeroing.)
8. For duct installation, screw the duct probe into the back of the enclosure and connect tubing from high (+) pressure port to duct probe. Drill a 1/4 hole in duct. Install sensor using gasket and screws provided.

It is important to note that the LED indicator will flash every 5 seconds for normal operation. The LED indicator will rapidly flash when applied pressure is greater than 110% of the selected range. The LED indicator will rapidly flash momentarily when the zeroing process is complete. If there is no output, check wiring, ensure power supply meets requirements, and verify control panel software is configured for correct output scaling. If there is a pressure reading error, verify switch settings and ensure sensor is used only on dry air or nitrogen.

WARNING

PRODUCT APPLICATION LIMITATION:
Senva products are not designed to be used as the lone device for life or safety applications. Senva products are not intended for use in critical applications such as nuclear facilities, human implantable device or life support. Senva believes a systems approach to safety is necessary for these types of applica-tions. Senva is not liable, in whole or in part, for any claims or damages arising from such uses.

IMPORTANT

IMPORTANT WARNINGS

• Only qualified trade installers should install this product
• This product is not intended for life-safety applications
• Do not install in hazardous or classified locations
• The installer is responsible for all applicable codes
• De-energize power supply prior to installation or service
• Forming a “drip-loop” (allowing tubing to dip below the level of the sensor hose barbs) is recommended to protect the sensor from damage caused by condensation.

INSTALLATION

1. Zero Button
2. Range Selection Dial
3. Output Selection Switch
4. Configuration Switches
5. Display
6. Pressure Sensor

WIRING DIAGRAMS

TYPICAL APPLICATIONS

Velocity: Use a pitot tube and plumb high (+) port to total pressure (Pt) connection and low (-) port to static pressure (Ps) connection to directly read Pt-Ps = Pv. Apply correction constant provided by pitot tube manufacturer.
Duct Static: Install a static pressure pickup tube approximately 2/3 of the way down the discharge air duct and plumb to high (+) port for positively pressurized ducts.
