Replacement sensors, (2) ea., 0-100 psid
Dwyer Series 490W Hydronic Differential Pressure Manometer is the most accurate and easy to operate manometer on the market. By using the Dwyer A-490W-4 Replacement Sensors (wireless transducers) and a versatile handheld, a single operator can monitor and balance a hydronic system in less time than traditional hydronic balancers. The Series 490W utilizes mobile technology to communicate via a Bluetooth connection with the transducers to monitor differential pressure and flow on up to three different valves.
The A-490W-4 Replacement sensor has a range of 0 to 100 psi (6.895 bar metric range) and a maximum pressure of 200 psig. Available engineering units include psi, ft w.c., in w.c., Pa, kPa, hPa, cm w.c., and mm w.c.
Applications:
- Refrigerant pressure testing
- Hydronic valve balancing
- Measure pressure drop across pumps
- Measure pressure drop across chiller and coils for freeze protection
