The INOR IPAQ-H/HX temperature transmitter is a universal and intelligent two-wire, in-head transmitter is intended for temperature and other
measurement applications. The combination of competitive pricing, functionality, and simple configuration has made the INOR IPAQ-H/HX temperature
transmitter the leading in-head transmitter for industrial temperature measurements. The IPAQ-HX model is an intrinsically safe version and is
CSA approved Class 1, Groups A-D.
INOR IPAQ-H/HX temperature transmitters are designed for applications with standard industrial demands on accuracy. To reach these demands, these
INOR transmitters use quality components and precision calibration equipment to reduce linearity and calibration errors. The INOR IPAQ-H/HX temperature
transmitter offers high long-term stability through internal "self-calibration" by means of continuous adjustment of important parameters after
comparison with accurate built-in references, contributing to a stability of ±0.1% per year. The Windows-based and user-friendly software, IPRO 4, is
used for transmitter configuration, documentation, monitoring, and calibration purposes.
The INOR IPAQ-H/HX temperature transmitter offers a SmartSense feature to continuously monitor the isolation resistance of thermocouples and three-wire
connected RTDs as well as the cabling between sensor and transmitter. These INOR transmitters react by forcing the output to a user defined level if the
isolation is too low. INOR IPAQ-H/HX temperature transmitters monitor sensor break and force the output signal to a user defined level when any sensor
lead is broken or disconnected. The sensor break monitoring can be switched off. The monitoring is furnished with a pulsed excitation current. This
eliminates the voltage drop in the lead wires (giving a measuring error), caused by a standard DC excitation current.
The INOR IPAQ-H/HX temperature transmitter can be set to automatically provide a recurring output current regardless of the input signal. The total time
for the controlled output is adjustable up to 30 minutes. The dampening function can be used to dampen undesired instabilities on the input signal. The
dampening time is approximately two seconds. The dampening time, is the time required in addition to the update time, for the output to reach 90% of its
final value after a step change has been applied to the input.
INOR IPAQ-H/HX temperature transmitters are loop-powered and will work on voltages down to 6.5V DC (8V DC for IPAQ-HX), thus giving good margins for high
loads in the current loop. Reversed polarity will not damage the transmitter. The INOR IPAQ-H/HX temperature transmitter is designed to fit inside connection
heads type DIN B or larger. The large center hole facilitates the pulling through of the sensor leads or an insert tube, greatly simplifying the mounting procedure.
INOR IPAQ-H/HX temperature transmitters are protected by a five-year warranty.
