Frequently Asked Questions (FAQ)
-
Q: What is a "draft range" specifically?
A: Draft range typically refers to very low differential pressure ranges, often used for measuring small pressure differences like those across filters, in low-flow gas lines, or for tank level under low pressure. -
Q: Can the EJA120A be used for liquid measurement?
A: Yes, it can be applied for liquid level measurement in tanks where the hydrostatic head pressure differential is within its specified low range. -
Q: Is the output signal customizable?
A: The standard output is analog (4-20mA). Digital communication protocols like HART may be available as an optional feature. -
Q: What are the typical mounting requirements?
A: It requires standard process connections (e.g., flanges or NPT threads). Installation should follow good practices for pressure instrument mounting. -
Q: Does it require special calibration?
A: It is calibrated for its specified range. Field recalibration may be possible depending on the model features. -
Q: What industries commonly use this transmitter?
A: Common applications include HVAC systems, clean room environments, light industrial processes, and water/wastewater treatment. -
Q: Are different pressure range options available?
A: The EJA120A is specifically for draft/low range. Other models for higher ranges may be available upon request. -
Q: What is the expected lifespan?
A: With proper installation and use within its specifications, it can offer a long operational lifespan typical of industrial-grade transmitters.
