The CALOG-LC II Calibrator is ideal for testing 4 and 6 wire loadcells, checking insulation breakdown, weighing system calibration and simulation. It can test a loadcells' zero balance, input resistance, output resistance, bridge balance, 50V DC insulation test from bridge to shield, bridge to housing and shield to housing. The CALOG-LOADCELL II Calibrator is a hand-held precision calibrator specifically designed for load cell testing, including insulation breakdown and weighing system calibration or simulation. Simply connect a strain-guage load cell to the spring terminals and press "TEST LOADCELL". The backlit graphics will display four or six wire, zero balance, input or output resistance and bridge balance. It can then carry out a 50 VDC insulation test form bridge to shield, bridge to housing and shield to housing. For system testing and calibration the CALOG-LOADCELL II Calibrator can simultaneously measure mV (with mass display), excitation voltage and mA. In source mode, used for load cell amplifier pre-calibration testing, it can source mV (with mass display), measure excitation and measure mA. In simulate mode it sources a mA signal to the control room or SCADA. The display can be in mA, mA and mass or mass and mA.
The Calog-LC Display is a portable, handheld unit that is able to display a Load cell value.The Lithium-Ion battery makes it possible to use the calibrator for a reasonable period of time as a portable load cell indicator in industrial plants or emergency situations. For longer applications, such as with a cattle scale, auxiliary power can be supplied via an external 12volt battery, charger or car cigarette lighter socket. In order to display mass, force, strain or torque from load cells the unit allows you to set the sensitivity in mV/V, range, decimal points and units.Zero trim can offset deadweight and span trim is available to increase the reading accuracy with the help of calibrated weights. Selections of software options such as tare, peak hold and auto-zero maintenance are included. The indicator can be used for one 350 Ohm or three 1000 Ohm load cells with a fixed 5Vdc excitation.
The DPM4004 load cell indicator is an easy-to-use precision programmable digital indicator for load cell & strain gauge applications. Inputs to the instrument include load cell input (6 wire) and two digital inputs for remote tare and remote peak hold reset (optional). The excitation includes sense feedback to compensate for cable voltage loss. Digital filtering for better stability and tare function is included as standard. Options include programmable analogue output, set-points (up to four alarms), peak or valley hold, RS-232/485 serial interfaces & more. A feature of these programmable indicators is the calibration method. The instrument can be pre-calibrated without load cell connections for zero & full scale values, & then on-site calibration can be done for deadweight offset & span calibration (single point test weight trim).
The DPM5004 LED load cell indicator is an easy-to-use precision programmable digital indicator for load cell & strain gauge applications. Inputs to the instrument include load cell input (6 wire) and two digital inputs for remote tare and remote peak hold reset (optional). The excitation includes sense feedback to compensate for cable voltage loss. Digital filtering for better stability and tare function is included as standard. Options include programmableanalogue output, set-points (up to four alarms), peak or valley hold, RS-232/485 serial interfaces & more. The DPM5004 has additional features. It has a 20-bit analogue to digital converter for ultrahigh resolution, and the excitation is user selectable for normal or barriered applications for intrinsic safety and it features user programmable display increments. A feature of these programmable indicators is the calibration method. The instrument can be pre-calibrated without load cell connections for zero & full scale values, & then on-site calibration can be done for deadweight offset & span calibration (single point test weight trim).
