PLEVA RR BoxThe RR is used for contact measurement of plani-form fabric webs such as textiles, bonded fabrics, paper, etc. The RR is based on measurement of the electrical resistance. This increases exponentially as the resi-dual moisture decreases. The special design of the tandem roller sensor al-lows the measurement of very low to high residual moisture content of natural and synthetic fiber blends.Electrostatic charges are discharged by the RR tan-dem roller itself and do not impair measurement.

ApplicationDesignThe measurement and control of residual moisture is of great importance for technological and econo-mic reasons at different steps in the production. The measurement is used e.g. behind dryer, stenter, sizing machines, cylinder dryer, humidifier or in front of padding mangle.

Measuring prinicple

- Sensor type RR 3.3 to measure over the width left - centre - right side

The new PLEVA RR box is designed to connect up to 4 preamplifier boards (HIMA8) for 4 individual measurement signals to one micro processor box.The new process box type RR Box is equipped with the latest state of processor technology and im-proved EMC protection. The modular electronics is easily expandable for additional sensors. The box has compatible mounting dimensions with previ-ous panel.I

Favourable price for RR WAvoid marks on the fabricRealiable and sturdySuitable for knitted fabrics••••Design of type RR WBoth metallic measuring rollers must be isolated with respect to the machine frame. Therefore both roller bearings must be mounted on isolating plates delivered by us.

Construction type RR Tandem rollerAccurate tandem roller sensor to measure the electrical resistance on fabric. The tandem roller use a damping system for high reproducibility and a swing out unit for lifting the sensors if required.

Residual moisture sensor with tandem roller Residual moisture sensors

RR Sensor

Application of RR W sensorThe PLEVA measuring device type RR W measures the residual moisture over the full fabric width on two guide rollers made of stainless steel.The sensor system RR W will be used at e.g. knitted fabric, or at surface sensitive fabrics like sanded, rai-sed or high-piled fabric after stenter frame.The measuring range of type RR W atCotton: 4 .. 20 %The measurement of synthetics or mixed fibres with synthetics is possible only with limitations for type RR W because of the high electro-statics that are produced for this type of fabric.

Application of RR Tandem roller sensorThe residual moisture measuring device RR with tandem roller sensor is used for lower humidity values or the measurement of synthetics or mixed fibres with synthetics.This sensor uses integrated protective devices to counter interfering electrostatic charges.The measuring range type RR Tandem roller de-pends on fibre, e.g.:Cotton: 1.0 .. 20 %Synthetics: 0.1 .. 5 %Polyamide: 0.2 .. 10 %Viscose: 1.7 .. 30 %Universal range: 0 .. 100 SCD (scale devision)Types: RR 1.1 = 1 Tandem roller / 1 signal RR 3.1 = 3 Tandem rollers / 1 signal RR 3.3 = 3 Tandem rollers / 3 signals

Sensor type RR W to measure over the full fabric width on two guide rollers

Design of type RR Tandem rollerThe sensor‘s first roller serves to devert most of the interfering electrostatic charges. The second devided measuring roller evaluate reliable residual moisture by the HIMA preamplifier.
