Maximum Load Resistance 50 (Vs-15) ohms Sealing Welded construction with sealed adjustments Electrical Connection 2 pinMIL-C-5015 Style Isolation 500 Vrms, circuit to case Hazard Rating UL and cUL certified Class I, Div. 2, Groups A-D, BASEEFA (Pending) Intrinsically Safe EEx ia IIB T4 (T amb = 413 o F) Environmental Rating NEMA 4 / IP 65 (Pending) Electromagnetic Compatibility CE Mark (Pending) Wiring Diagram Field Adjustments Threshold Adjustment Impact has been used successfully to measure mechanical looseness on large reciprocating compressors for several years. This new Impact Transmitter combines the benefits of this measurement with the convenience of 4-20 mA loop powered sensor technology. It has a built-in piezoelectric crystal sensing element, and uses a timing function as part of it’s severity determination. An impact event counter and memory device is used to record events meeting a preset amplitude threshold level. The 4-20 mA signal represents the number of impact events above the threshold level that occur within a preset time window called the reset time. Mechanical impacts are both measured and qualified within the transmitter. The result is a current output proportional to impact severity. The Model IP1 Impact Transmitter detects: Loose rod nuts Cracked rod Broken or loose bolts Excessive clearance in the slipper Typical Mounting Distance Piece or Spacer Crank Shaft Cross Head IP1 Impact Transmitter Compressor Cylinder Mounting Bolt Reset Time Adjustment NOTE: Remove sealing screws to gain access to adjustment potentiometers

Electronic Impact Transmitter - Model IP1 The output of the IP1 impact transmitter is a 4-20 mA signal proportional to the number of impact events over the threshold in a set time period. The relationship between the mA signal and the number of impact events remains the same. The time frame over which the events are measured can be changed. This will allow you to match the measuring time frame with the RPM range of your equipment. Chart #1 indicates mA output vs impact events over the set threshold. Waveform: Signal from machine with mechanical looseness Waveform being detected by IP1...
