Life Cyclic Durability Testing
Environment Associates can provide everything you need for cyclic durability testing and performance fixturing. Services include mechanical cycling to a position or load, fatigue cycling to a fixed load, rotational torque cycling, and simple push/pull cycling. EA can design your fixture with electro-dynamic, air, or hydraulic assistance to mechanically move your part. All of our fixtures can be manufactured to withstand a wide range of temperature, humidity and vibration inputs. If required, forces can be monitored electronically, using a wide variety of inputs (i.e. strain gages, load cells, rotational transducers, thermocouples, shunts, and more). EA can create holding and check fixtures to perform “pre” and “post” evaluation for dimensional issues that may occur during testing. EA can provide fixtures for single tests run internally for EA test labs and can manufacture fixtures to be purchased directly by the customer for their internal use.

SparkFun Current Sensor Breakout
INA169
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.

Service Ground Test Set
900
TESCO’s Service Ground Test Set has been designed to check the condition of the ground connection on a secondary service. If for any reason the ground connection has a resistance, this can be immediately detected by the Test Set. The Service Ground Test Set consists of a voltmeter which can be shunted by a resistance of 60 ohms. The voltmeter is of the suppressed zero type with a double range, from 65 to 130 or from 130 to 260, and can be used for checking service voltage independently of the ground test.

Shunt Voltage References
Analog Devices offers a broad line of shunt precision voltage references that combine excellent accuracy and temperature stability with low noise and small packages. These devices operate in a manner that is functionally equivalent to a Zener diode. The bias current must be set higher than the sum of the maximum quiescent current of the voltage reference and the maximum expected load current. Since shunt voltage references are typically biased with a resistor, the voltage reference can operate on a wide range of input voltages.

Stand Alone/ Bench Top Load Cell Amplifier/ Conditioner Module
MODEL TMO-2A
The TMO-2A Transducer Modules is a complete differential amplifier/signal conditioners with self contained power. The unit 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. Zero to full scale output is specified at 4-20 mA. The TMO-2A 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. The removal of a single capacitor will increase the frequency response DC to 60K Hz for dynamic data applications.
