Low Profile Force Sensor from Dytran Instruments

The new Dytran model 1212V series are low profile ring style IEPE force sensors, which the industry commonly refers to as “force washers”, due to their similar appearance. These sensors are designed to measure rapid or slowly changing dynamic forces in machinery and other applications where a through stud or bolt holds the sensor in place in a preloaded condition

The model 1212V can measure vibratory compressive forces over a wide frequency range and unidirectional pulsing forces from punch and forming presses and other repetitive force applications as well as impact forces. The 1212V series are offered with either a 1.0, 2.5 or 10 mV/lbf sensitivity, having full scale ranges of 5000, 2000, or 500 lbs respectively. As an IEPE sensor, the 1212V series features built-in electronics, eliminating the need for an external charge amplifier and converter, although for repetitive force applications a special zero clamp circuit may be required. These models are all just 4mm thick with an external diameter of 19mm and an internal hole of 4mm, and are supplied with an integral 10 ft cable with a BNC plug termination. Design of the model 1212V design features a quartz sensing element, operating in compression mode and packaged in a rugged stainless steel housing weighing just 8 grams. The working temperature range is from -51 to +121 degC.
