Product Details
The inductive transducers PR9350/04 or the set K20-315 serve the measurement of static and dynamic displacements, and in connection with a carrier frequency measuring bridge, of physical quantities (tensile and compressive forces, pressure of gases and liquids, thickness of materials, transverse moments) which may in any way be converted to linear movements by using relevant accessories.
The special features of these transducers are a high resolution over the entire measuring range, small hysteresis, compact construction, and the small mass of the tracing pin (solenoid plunger). Thus, the controlling forces on the measuring target may be neglected.
The temperature drift is extremely small because the compensation coil is wound directly over the measuring coil.
The installation of these transducers is imaginably easy. The transducer permits dynamic measurements up to 1250 Hz.
The differential coil of the PR9350/04 series consists of a coil form with two windings and a tracing pin with a ferromagnetic core within the coil. If the tracing pin is placed precisely in the middle of the coil, the impedance of both windings is identical. The impedance of the windings will increase on one side and decrease on the other side – if the tracing pin with the ferromagnetic core moves from the middle position to one end of the transducer.
By complementing the windings with resistors to a Wheatstone bridge, and by supplying this bridge with a carrier frequency, the measuring output of the bridge reads a voltage which is proportional to the displacement of the tracing pin. The tracing pin is freely movable and has a threaded rod (M3) for the mechanical adaptation to the measuring target. On top of the housing, there is a 3-pole Cannon socket for the electric connection. Inductive transducers of type PR9350 or the set K20-315 are preferably used with the A6500-LC LVDT Converter and the A6500-UM Universal Measurement Card.
The PR9350/04 is available with several measuring ranges from ±12 mm up to ±150 mm. The set K20-315 consists of a PR9350/04 sensor mounted in a housing inclusive connection cable.

Incoming goods inspection:
Check the content of the shipment to ensure that it is complete; visibly inspect the goods to determine if the device may possibly have been damaged during transport.
If the contents are incomplete or if any defects are observed, a complaint must be filed with the carrier immediately. Moreover, the responsible Emerson sales organization must be informed to enable the replacement of the device. In this case, a non-detachable tag wicustomer'sustomer name and defect observed must be attached to the device.
Work with the opened device should be performed only by a specialist who is familiar with the associated hazards.
