PCB Piezotronics, Inc. 4-20 mA Output Velocity Sensor 640B02

The PCB Piezotronics 640B02 is a 4-20 mA output velocity sensor designed for industrial applications. It has a measurement range of 0.0 to 2 in/sec (0.0 to 50.8 mm/s) and operates within a frequency range of 180 to 60,000 cpm (3 to 1 kHz). The sensor features a broadband resolution of 0.01 in/sec (0.26 mm/s) and a non-linearity of ¬±1%. This sensor is built to withstand harsh environments, with an operating temperature range of -40 to 185 ¬8F (-40 to 85 ¬8C) and an IP68 enclosure rating, ensuring protection against dust and water ingress. The excitation voltage required for operation is between 12 to 30 VDC, and it has a settling time of less than 15 seconds. Physically, the sensor measures 1.0 in (25.4 mm) in diameter and 2.6 in (66 mm) in height, weighing 4.7 oz (131 g). It features a stainless steel housing with a welded hermetic seal, and it is equipped with a 2-pin MIL-C-5015 electrical connector. The sensor is suitable for various mounting applications, utilizing a 1/4-28 UNF thread with a recommended torque of 3 to 5 ft-lb (4 to 7 Nm). Additionally, the 640B02 is approved for use in hazardous areas, complying with multiple safety standards. This makes it a reliable choice for engineers seeking a robust and precise velocity sensor for their projects.
