Bidirectional -50 to +50 Pa diff pressure transmitter with user calibration adjustment

Request Price

Enhance your hvac or filter monitoring system with this accurate and durable low differential pressure transmitter featuring user-adjustable zero and span.

The DPS pressure transmitter is specifically designed for applications requiring precise bidirectional differential pressure measurement in the low range of -50 to +50 pascals. This makes it ideal for monitoring pressure differences across filters, fans, or in cleanroom environments where subtle pressure variations are critical. The inclusion of user-accessible calibration adjustments for zero and span settings offers a significant advantage. This feature allows for in-situ calibration, eliminating the need to remove the transmitter from its installation, saving time and effort during maintenance or when process conditions change.

The 2-wire, 4-20mA output signal provides a widely compatible and robust analog interface for integration with various control systems, data acquisition devices, or PLCs. The transmitter operates on a 12-31Vdc supply, making it suitable for a range of industrial power sources.

The overpressure protection of 5x the full-scale range ensures the transmitter’s durability and reliability even under unexpected pressure surges or fluctuations. This is particularly important in applications where transient pressure events might occur, protecting the sensor from damage and maintaining measurement integrity.

The 6.6mm diameter x 11mm barbed pressure connections offer a secure and leak-free method for attaching tubing, simplifying installation and ensuring reliable operation. This type of connection is commonly used in pneumatic and low-pressure fluid systems, making it a versatile choice for various applications.

For example, in a cleanroom environment, the DPS can be used to monitor the pressure differential between different zones, ensuring proper airflow and containment. In a filter monitoring application, this transmitter can accurately measure the pressure drop across the filter media, indicating when the filter needs to be replaced. In HVAC systems, it can be used to measure the pressure difference across a fan or blower, providing valuable data for system optimization and control.
