Dwyer Instruments 629C03CHP2E5-S1-3V Pressure Transmitter
The Dwyer Instruments 629C-03-CH-P2-E5-S1-3V is a rugged wet/wet differential pressure transmitter engineered for precise monitoring of compatible liquids and gases in demanding HVACR environments. Featuring a 0 to 25 psid range and ±0.5% full-scale accuracy, this unit utilizes dual 316L stainless steel sensors to deliver a stable 4-20 mA output. This specific configuration includes an integrated 3-way valve manifold, a critical feature for contractors that allows for easy zeroing and maintenance without breaking the process loop. The internal removable terminal block and adjustable zero/span buttons are protected within a NEMA 4X conduit housing, ensuring reliable performance in wash-down or outdoor applications. Designed for 1/2" female NPT conduit electrical connections and 1/4" female NPT process fittings, it integrates seamlessly into chiller monitoring, pump control, and heat exchanger systems. The dual-sensor architecture minimizes moving parts, providing the long-term stability and fast 400 msec response time required for high-stakes differential pressure measurement.
Key Benefits:
- Integrated 3-Way Valve: Simplifies field commissioning and protects the internal sensors from potential water hammer during startup.
- NEMA 4X Enclosure: Provides high-level corrosion resistance and protection against harsh environmental conditions.
- High Precision Monitoring: Delivers 0.5% accuracy, covering linearity, hysteresis, and repeatability for critical efficiency tracking.
- Versatile Media Compatibility: Suitable for both air and compatible liquid systems, including glycol loops and hydronic circuits.
- Simplified Wiring: Features a removable terminal block and 1/2" NPT conduit connection to reduce installation labor.
Common Questions:
What is the maximum line pressure for this transmitter?
The standard 0-25 psid model with the 3-way valve manifold is rated for a working pressure of 50 psi and an overpressure limit of 100 psi. Exceeding these limits may result in a calibration shift.
Can I use this 4-20 mA transmitter with an AC power supply?
Yes, the 629C series is versatile; while typically used in 2-wire DC loops (10-35 VDC), it can also be powered by an isolated 16-33 VAC source in 3-wire configurations.
How do I zero the unit after installation?
The transmitter features accessible push buttons for zero and span adjustment located under the removable NEMA 4X cover, allowing for quick field calibration using the 3-way valve to shunt the high and low ports.
