General Purpose - Encore Electronics, Inc.

Encore offers a complete line of General Purpose Signal Conditioning instrumentation to meet even the most demanding requirements. Packaged as interchangeable two-channel plug-in modules, Encore’s broad product line includes frequency to voltage converters, strain gage amplifiers, accelerometer conditioners, digital voltmeters and DC power supplies. All of our systems feature a common CAL input on the rear of the rack which allows for calibration of the entire rack. Calibration function varies based on the modules installed. For example, the Model 633 applies a shunt calibration resistor across the bridge, while the Model 149 applies a reference charge source to the input. Contact Encore today and let our team of design engineers help you determine which of our products is best for your application.

Variohm Eurosensor Ltd

Variohm Eurosensor Ltd

The STL Force Sensing Tension Links are a series of unique force sensors. The Tension Links utilize the internal strain gage process sucessfully and are used in bolts, load pins and flat load cells. The sensing element consists of a strain gage bridge circuit internally installed in a small hole along the longitudinal axis. This unique arrangement provides a most effective means for the protective sealing of the internal electronics while minimizing the adverse effects of extraneous torsion and bending loads.

High Elongation Extensometers

Model 3800

Jinan Testing Equipment IE Corporation

Model 3800 - Jinan Testing Equipment IE Corporation

The main body of this unique extensometer remains stationary during testing, held in position by the adjustable magnetic base included. Only the very light, small traveling heads move as the sample elongates during a test. These attach to the sample with small spring clips. Each head pulls a cord out from the extensometer as the head moves. These models use high precision, low friction potentiometers, and, as a result, have a wide range of factory selectable outputs. The extensometer is driven by an excitation voltage and has output proportional to the input. They can be provided with high level outputs (approximately 2-8 VDC) or ones that mimic strain gaged devices (2-4 mV/V). When set to mimic strain gaged extensometers, the Model 3800 can be used with virtually any signal conditioning electronics designed for strain gaged sensors. The potentiometers employ a hybrid wire wound around conductive plastic, which provides excellent long term stability. The output from the extensometer is readily interfaced with most existing test controllers, and may be directly input to data acquisition systems and chart recorders. Please let us know at the time of order what type of output and connector you require.

Model 3542L - Jinan Testing Equipment IE Corporation

The dual flexure design makes the 3542L very rugged and insensitive to vibrations. These extensometers are designed for testing a wide range of materials including metals, plastics, composites and ceramics. Epsilon’s Model 3543 is recommended for applications requiring long gauge lengths and larger measuring ranges.The Model 3542L comes standard with Epsilon’s quick attach kit, making it easy to mount the extensometer on the test specimen. The quick attach kit can be removed, allowing mounting of the extensometer with springs or rubber bands.The 3542L extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment.

Strain Sensors

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Conventional strain sensors are based on strain gage technology. In order to effectively measure the strain values in a force or load measurement application, a full, 4 element strain gage bridge circuit is utilized. The configuration is known as a Wheatstone Bridge Circuit. A Wheatstone Bridge has a very linear output in it’s midrange. That being considered +100% to -100% of range. Unfortunately, a Wheatstone Bridge becomes non-linear above the upper and lower extremes of range. Therefore, significant errors can result above the end points when attempting to take precision measurements. It is particularly important to take accurate measurements in some R&D or control applications. To avoid the mentioned error issues, PCB manufactures quartz piezoelectric strain sensors that output the same mV/microstrain sensitivity throughout the entire useful range. Thus, accuracy is improved and control requirements are enhanced that may occur at positive extremes of the measurement range. The models RHM240 and model 740B02 series sensors are the strain sensors for these applications.

Jinan Testing Equipment IE Corporation

Model 3548COD - Jinan Testing Equipment IE Corporation

These COD gages mount on a water-cooled bracket, which is mounted on the furnace side cut-out or with optional load frame support brackets. The standard temperature version (to 1200℃) is supplied with high purity alumina rods. The high temperature option is furnished with alpha grade silicon carbide rods. Rods are made to order to the length required for your furnace. Mounting brackets may be integrated with the furnace cut-out. Epsilon can also provide optional load frame mounting brackets to fit your test frame. Contact edges on the test sample should be somewhat rounded (not sharp knife edges) for best performance with this model. The Model 3548COD extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added.
