The IPAQ-LPLUS is a high-performance, universal and
intelligent 2-wire DIN rail transmitter for temperature and
other measurement applications. The outstanding combination of
excellent specifications high functionality and simple
configuration makes IPAQ-LPLUS the obvious choice in demanding
applications. They offer low linearity and calibration errors,
with the combination of a high-efficient 40-point linearizaion
and the use of quality components and precision calibration
equipment, low ambient temperature influence, and high
long-term stability. The Windows™ -based and user-friendly
software, IPRO 4, is used for transmitter configuration,
documentation, monitoring, and calibration purposes.
The IPAQ-LPLUS also offer two ways of improving the
measurement with temperature sensors: sensor error correction
(comparing the known sensor errors to the standard curve) and
system error correction (by exposing the sensor to one or two
accurately- measured temperatures). The SmartSense feature
continuously monitors the isolation resistance of
thermocouples and three-wire connected RTDs, as well as the
cabling between sensor and transmitter. The Smart Filter
detects the difference between fast signal changes and
electrical noise, e.g. ripple and spikes, on the input. The
smart filter offers a superior combination of very short
response time for the input signal and high noise immunity.
The dampening function can be used to dampen undesired
instabilities on the input signal. The dampening time can be
set between 0 and 10 seconds in intervals of one second. The
dampening time is the time required, in addtion to the update
time, for the output to reach 90% of its final value after a
step change has been applied to the input.
The IPAQ-LPLUS is loop-powered and will work on the
voltages down to 7.5V DC thus allowing for high loads in the
current loop. |
