Transducer LCA-RTC成本低，專用于單電橋式稱重傳感器或者扭矩傳感器的信號(hào)調(diào)節(jié)。靈敏度范圍：0.5 mV/V to 10 mV/V, 頻寬100 Hz to 30kHz，放大輸出信號(hào)有：0 to ±5V, 0 to ±10V, 0-16 mA, 0-20 mA or 4-20 mA.

The LCA-RTC Module provide low-cost, dedicated signal conditioning for a single bridge type load cell or torque sensor. Model LCA-RTC comes with removable screw-clamp terminal connectors, which accept wires without soldering. On- board jumper selections include sensitivities from 0.5 mV/V to 10 mV/V, bandwidths from 100Hz to 30 kHz, and amplified outputs of 0 to ±5V, 0 to ±10V, 0-16 mA, 0-20 mA or 4-20 mA. Zero and span adjustments are via precision 25-turn low-tempco metal film potentiometers. The units can be operated next to the sensor with 4-wire hookup or at distances up to 1 km (3300 feet) with 6-wire hookup. An onboard 87.325 kΩ resistor allows easy shunt calibration at the push of a button. Provision is also made for a userfurnished calibration resistor. Power requirements are 11.8 to 26V DC with load currents from 10 to 60 mA, the latter applying when the unit provides 10V DC excitation to a 350 ohm load cell and delivers a 20 mA analog output.
