Controlling the head pressure helps maintain pressure drop across the metering device and prevents the evaporator from freezing, in the case of air conditioning, and excessive freezing in refrigeration systems.
It can detect a low pressure differential across high static pressures, allowing for improvement of measurement accuracy and providing the ability for the system to react quickly to changes.
ACI’s compact sized, A/MLP Series Pressure Transmitter is designed specifically for panel mount, duct and OEM installations. Pressure ranges from +/- 0.5 inch to +/- 20 inches of water column.
The 63 Series of transmitters has expanded, and provides accuracy, long up-time, and stability regardless of the environment or project budget, according to the manufacturer.
