Bolt Extensometers for Proof Load Testing
Model 3565
-
Jinan Testing Equipment IE Corporation
The Model 3565 uses hard conical points to contact the bolt at the center of the head and at the bottom. It is fully adjustable for different length bolts ranging from 25 mm (1 inch) in length to 150 mm (6 inches) standard. Extension beams are available for longer bolts. The standard maximum measuring range is 1.25 mm (0.05 inches). Generally, on longer bolts this extensometer will be self-supported without requiring any centering marks or punch marks on the bolt. For shorter bolts these marks may be required. If the conical pins are sharp, marks are often not needed even on the shortest bolts.The extensometer has a zero adjustment screw to adjust the length between the contact pins. This is used to set the output voltage to zero, which corresponds to the correct starting position for the test. It also includes a breakaway lower arm. In the event a bolt should fail, the breakaway arm snaps free, helping to prevent damage to the extensometer. This is easily re-installed. In the event that bolt failures are likely during a test, it is recommended the user attach a cord around the upper part of the beam and tie the other end to the test frame to prevent the extensometer from falling. The conical point contacts included with the extensometer are made from tungsten carbide.The Model 3565 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.

Transformer Resistance Testing
-
Transformer insulation resistance deterioration is one of the most common causes of transformer failure: a failing transformer is a costly replacement in an electrical system with the potential for a long downtime. If you fail to maintain your transformer with regular insulation resistance testing (as can be carried out by the Megger Transformer Ohmmeter (MTO) series of transformer test equipment) then it’s likely to fail before reaching its maximum operating life.

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.
