SPECIFICATIONS
Thank you for choosing an HK Instruments DPT-Priima differential
pressure transmitter. DPT-Priima is a high-precision differential pres-
sure transmitter engineered especially for cleanrooms and other high
accuracy applications. DPT-Priima has an automatic zero point calibra-
tion and is optionally available with span point calibration, local display
and calibration certificate. The versatility of the device is enhanced
by eight selectable measuring ranges and by outputs with a voltage or
current signal.
DPT-Priima is commonly used in applications requiring high
measurement accuracy:
• monitoring pressure in cleanrooms
• monitoring pressure difference across the building envelope
• monitoring pressure and flow
