  SE SERIES PROXIMITY PROBE SYSTEMS

Introduction to proximity probe systems

 

Proximity  probe  transducers  have been widely used in measuring  the  static  and  dynamic  distance  between  the target and the probe. With its high quality, highly reliable, and long life cycle, Spectrum’s SE series proximity probes have been used to measure shaft vibration, radial and axial shaft position and differential expansion between case and rotor. In addition, the proximity probe transducer can be used for diagnostic purposes, providing solutions to problems that may develop on rotating machinery, including early shaft crack detection, misalignment of the shaft within the machine casing, rotor imbalance, abnormal bearing wear. With no moving parts to wear out or degrade, a proximity probe system can last a very long time before requiring calibration or service. This allows installation of the proximity probe transducer during normal machine maintenance outages and connection of the transducers to monitoring and diagnostic equipment at a later date.

Probe

SE series proximity probes come with diameters of 5, 8, 11, 16, 18 and 25mm threads. The probe can be selected in English or Metric threads - you can request the reverse mount option.  Each probe includes a user specified integral cable in length of 0.5m, 1.0m, 5m or 9m as standard. 

 

Extension Cable

You can select various extension cable lengths based on the probe cable length.  Extension cables of 4m, 4.5m, 8m or 8.5m can be attached to the probe to bring the total cable length to either 5m or 9m – which is the required cable length for optimum driver performance, accuracy and linearity.

 

Driver

Using the latest in electronic design and assembly, the driver of SE system has unmatched accuracy in industry today. The total length of cable between the probe and the driver should be either 5m or 9m. The distance between the driver and the monitor can be up to 300m (1000 ft)      

 

To Order : please provide the following probe system information for each measurment point:

Commissioning / Calibration Tools for Proximity Probes

Spectrum Instruments Ltd's Model PC-100 is a battery operated, easy-to-use instrument that allows an operator to check a proximity probe's condition by measuring the sensor’s GAP voltage on its integral LCD display. A series of 10 LEDs in a bar graph format aids the user as he adjusts the GAP of the proximity probe looking for the optimum gap.

An additional constant current function also allows this device to simulate mid scale of any 4-20ma loop thus providing a quick check of loop integrity.
