The Reciprocating Machinery Protector (RMP) model 649A01 from PCB Piezotronics, Inc. is designed to monitor machinery performance with a 4-20 mA output. It operates effectively within a machinery RPM range of 240 to 10,000 counts per minute and features a time window adjustable from 0.1 to 4.0 seconds. The device can detect vibration thresholds between 2 to 50 g, making it suitable for various applications. This model is built with a piezoelectric accelerometer and housed in a stainless steel casing, ensuring durability and reliability in harsh environments. It has a wide operating temperature range from -40 to 212 ¬8F (-40 to 100 ¬8C) and a storage temperature range of -40 to 257 ¬8F (-40 to 125 ¬8C). The electrical specifications include an excitation voltage of 15 to 30 VDC and a load resistance of 50(Vs-15) Ohm, with excellent electrical isolation greater than 10^8 Ohm. The device weighs 7 oz (198 gm) and has dimensions of 1.25 inches in hex size and 2.60 inches in height. It features a 1/4-28 UNF mounting thread and requires a mounting torque of 3 to 5 ft-lb (4 to 7 Nm). The RMP model 649A01 is suitable for applications requiring precise monitoring of reciprocating machinery, providing engineers with a reliable solution for vibration analysis.
Loop Powered 4-20 mA Output Reciprocating Machinery Protector (RMP)
The patented Reciprocating Machinery Protector offers a 4-20 mA output that is calculated by counting the number of impacts, comparing them to the vibration thresholds and weighting them.
