2041 Panelmeter for strain gauge sensors • Strain gauge sensors with 4- or 6 -wire connection • Excitation voltage 10V to sensors, max 150 mA • 6-digit processor-based LED-display • Settings via front panel keys • Output 0/4..20 mA, 0..10 V • Serial output RS-232 or RS-485 •2 - 4 alarm relays • Display taring via front panel key • Measuring accuracy < 0,05 % of span • Power supply 85..240 VAC or 12..32 VDC/ 24 VAC The versatile panelmeter 2041 is designed for strain gauge sensors. Strain gauge sensors can be connected with 4 or 6 wires. The 6-wire connection removes the lead wire resistance, as bridge voltage is measured from the sensor poles, and therefore it is recommended for applications requiring very high accuracy. The panelmeter provides 10 V excitation voltage for sensors, max. four 350 ohm sensors. Options to the 2041 include output 0/4-20 mA , 0-10V, 2..4 alarms or serial output RS-485/232. Display scaling and taring is easy via front panel keys. Scaling can be carried out in two different ways, either by applying the mV values of the bridge or using the teaching function. The teaching is done by first loading the sensors with the min. weight and then with the max. weight, after which the meter will automatically count the scaling. In applications where the sensor loading is not in balance a separate serial connection unit of the sensors 20 SA-4 can be used to prevent the nonlinearity caused by the imbalance. There are two power supply alternatives: one for line voltage 85..240 VAC and the other 12..32 VDC/ 24 VAC, both galvanically isolated from input and output. Analog conversion is done by a 16-bit AD-converter (resolution 1/64000) and the number of measurements is 3 per second. Separate passwords can be set for access to the configuration menu and alarms. The display can be damped with a digital filter if necessary. The number of decimals on the display is selectable. Front panel protection rating is IP65. The panelmeter series 2000 is very flexible and easy to modify by changing input cards for different kinds of sensors, such as temperature sensors, pulse sensors, serial inputs etc. The modification does not require any calibration. The optional cards are the same for all the instruments in this product family. Each panelmeter type has its own datasheet. Separate field enclosures can be supplied for 1 to 3 panelmeters.The 2041 is also available in the field display series, model 2800-2041.
