Description
The Veris PWLX04BP is a differential air pressure transmitter designed for precise measurement of low-pressure air differentials in HVAC systems. With a 0–4 inches water column (WC) pressure range, this transmitter is ideal for monitoring airflow across filters, fans, and duct systems. It provides a 4–20 mA analog output for reliable integration with building automation systems (BAS) and controllers. The PWLX04BP supports accurate pressure tracking to help maintain proper ventilation, detect clogged filters, and ensure overall system efficiency in commercial and industrial environments.
Key Features:
- Differential air pressure transmitter for low-pressure HVAC applications
- 0–4" WC pressure range for duct and airflow monitoring
- 4–20 mA output for BAS and control system integration
- Ideal for filter status monitoring and airflow verification
- Provides accurate and stable pressure measurement
- Durable construction for long-term use in commercial and industrial HVAC systems
