IPAQ-H/IPAQ-HX TEMPERATURE TRANSMITTERS
|
IPAQ-H is a universal and intelligent, isolated 2-wire In-head transmitter for temperature and other measurement applications.
IPAQ-HX is the Intrinsically Safe version for use in Ex-applications.
The combination of competitive pricing, functionality and simple configuration has made IPAQ-H and IPAQ-HX leading in-head transmitters for industrial temperature measurements.
The Windows based and user friendly software, IPRO4, is used for transmitter configuration, documentation, monitoring, and calibration purposes.
