New Contact-Free Capacitive Level Switch  Allows for Complete Media Compatibilit

 

Sensortechnics’ new CLW series detects point levels of liquids and granular or pulverised materials without contacting the media. The user can easily adjust a high and low switch point with a hysteresis of less than 25 mm. The CLW device uses a new non-invasive capacitive sensor technology and allows for complete media compatibility and sterility. Due to its miniature size these level switches can be perfectly integrated into OEM devices. The CLW sensor can be mounted to the outside of a container or vessel and is able to measure through almost any non-metallic wall material. The level switch is highly flexible and can be easily calibrated to measure to the desired levels, media and application set-up. The CLW series achieves a very high accuracy and reliability due to an additional reference electrode which compensates for all changes in ambient environmental conditions such as temperature and humidity. Additionally, Sensortechnics can also provide continuously measuring level sensors based on the same contact-free capacitive technology ...

Ultra Low Range Precision Load Cells

 

Sherborne Sensors has announced the North American launch of the SS2/SS3 series, a family of ultra-low range precision load cells, designed for aerospace, automotive, medical, R&D and general industry applications where extremely low force measurements are required. The SS2/SS3 series offers full range measurement capabilities to 60 grams, with a 12mV/V full scale output and virtually infinite resolution, enabling low forces to be resolved down to just a fraction of one gram. Bonded semiconductor strain gage technology confers excellent sensitivity, and eliminates the fragility associated with non-bonded strain gage types. The robust design of the SS2/SS3 series features excellent immunity to the effects of eccentric loading, side loading and bending moments, with added versatility of precision measurement capabilities in either tension or compression mode. Low deflection and high-frequency response characteristics of the SS2/SS3 series are suitable for measuring both peak and transient forces over an operating temperature range of -20 to +90 °C ...

Press Force Sensors

 

The well established Kistler press force sensors are based on the piezoelectric measuring principle. The force acting on the quartz element generates at the output of the sensor a proportional electric charge, which is converted by the series-connected measuring amplifier (such as ICAM Type 5073A) into a process signal suitable for evaluation (typically 0 ...10 V). The new sensor Type 9383A extends Kistler's successful series of piezoelectric press force sensors. The sensor preloaded ready for mounting with the three standardly calibrated measuring ranges of 0 ... 3 kN, 0 ... 30 kN and 0 … 300 kN is ideal for measuring both dynamic and quasistatic forces ...
