Current Sensing
-
voltage-output, current-sensing amplifier family that integrates an internal shunt resistor to enable high-accuracy current measurements at common-mode voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device is a bidirectional, low- or high-side current-shunt monitor that allows an external reference to be used to measure current flowing in both directions through the internal current-sensing resistor sensor. The integration of the precision current-sensing resistor provides calibration equivalent measurement accuracy with ultra-low temperature drift performance and ensures an optimized Kelvin layout for the sensing resistor is always obtained.

Stand Alone/ Bench Top Load Cell Amplifier/ Conditioner Module
MODEL TMO-2
-
The TMO-2 Transducer Modules is a complete differential amplifier/signal conditioners with self contained power. The units provide excitation, balance and span adjustment via precision 10 turn pots, and shunt calibration necessary to couple a user supplied bridge type transducer to an indicating instrument. Full scale output is specified at plus or minus 10 VDC. The TMO-2 provides a floating shunt calibration circuit which applies calibration at the transducer, thereby eliminating errors due to line losses. The excitation supply incorporates a Wagner Ground to greatly improve Common Mode Rejection. The factory set bandwidth of the module is narrow to improve stability for applications such as weighing scales. The removal of a single capacitor will increase the frequency response DC to 60K Hz for dynamic data applications.

Crossing Control Bypass Switch
XCBS-DL
-
The XCBS-DL is permanently wired into each crossing warning system, and can be configured with either a removable or non-removable bypass key. Simply connect the track connection harness to the designated track connection terminals. To prevent unnecessary operation of the crossing warning system, insert the key and select "bypass", rotate the knife switch to "bypass" and the crossing is disabled. When in the "bypass" position, a Dummy Track Load is connected to the track wire connections in parallel with the rails and the crossing approaches are shorted, preventing unnecessary activation when track equipment is working in the crossing approach circuit. The opening of one track lead may be desired to prevent unnecessary activation with intermittent shunting on the crossing approaches close to the crossing.

The INA169 is a “high-side current monitor,” which means that you place a resistor (a “shunt resistor”) on the positive power rail and the INA169 measures the voltage drop across that resistor. The INA169 outputs a small current based on the measured voltage drop. If you place a resistor from the output of the INA169 to ground, you can measure the voltage at the output.

Dual Wide Range Power Monitor
LTC2992
-
The LTC®2992 is a rail-to-rail system monitor that measures current, voltage, and power of two supplies. It features an operating range of 2.7V to 100V and includes a shunt regulator for supplies above 100V. The voltage measurement range of 0V to 100V is independent of the input supply. Two ADCs simultaneously measure each supply’s current. A third ADC monitors the input voltages and four auxiliary external voltages. Each supply’s current and power is added for total system consumption. Minimum and maximum values are stored and an overrange alert with programmable thresholds minimizes the need for software polling. Data is reported via a standard I2C interface. Shutdown mode reduces current consumption to 25μA typically.
