Time-Resolved Electrochemical Quartz Crystal Microbalance
400C Series
The quartz crystal microbalance (QCM) is a variant of acoustic wave microsensors that are capable of ultrasensitive mass measurements. Under favorable conditions, a typical QCM can measure a mass change of 0.1-1 ng/cm2. QCM oscillates in a mechanically resonant shear mode under the influence of a high frequency AC electric field which is applied across the thickness of the crystal. Figure 1b below shows an edge view of a QCM crystal undergoing oscillatory shear distortion. The central portions of the top and bottom of the crystal are coated with a typically disk-shaped thin metal film (e.g., gold).

Shear Beam LoadCells
Shear Beam LoadCells are designed for low profile scales and process applications. These loadcells should be mounted on a smooth flat surface using high strength hardend bolts. The mountaing holes are at the opposite end to where the cell is loaded. Some of the larger Shear Beam Loadcells use multiple mounting holes to allow extra bolts to hold them in place and keep them from stretching under the stress.

Averaging Extensometers for ASTM D5656 Shear Tests
Model 4013
Jinan Testing Equipment IE Corporation
The Model 4013 extensometer meets the requirements of ASTM D5656 for measuring the strain properties of an adhesive in shear. It uses different contact point spacing compared to the extensometer shown in D5656. This makes it much easier to mount and eliminates the slippage problems associated with the design shown in the ASTM standard. The Model 4013 is available with all of Epsilon’s temperature configurations. It has a 3.0 mm (0.12 inches) full scale measuring range. The conical point contacts included with the extensometer are made from tungsten carbide.The Model 4013 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.

The 2291 Guided Wave Radar level transmitter is designed for continuous level measuring of conductive or non-conductive liquids, pulps and solids. The 2291 level gauge operates based on the well-known TDR (Time Domain Reflectometry) principle. Micropulses are sent along a probe guide at the speed of light. As soon as the impulse reaches the surface of the medium, it is reflected back to the electronic module. Level distance is directly proportional to the flight time of the impulse.
