Inor IPAQ-L/LX Temperature Transmitter

Inor IPAQ-L/LX 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-L/LX 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 IPAQ-L/LX 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-L/LX 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-L/LX 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-L/LX temperature transmitters are loop-powered and will work on voltages down to 7.5V DC (8V DC for IPAQ-LX), thus giving good margins for high loads in the current loop. Reversed polarity will not damage the transmitter. The Inor IPAQ-L/LX 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-L/LX temperature transmitters are protected by a five-year warranty.
