- Page 2 PY SERIES HIGH OPERATING TEMPERATURE DISPLACEMENT TRANSDUCER INTRODUCTION This series of non-contacting displacement transducers is available in three different measuring ranges and these ranges are available in two different operating temperature ranges. The PYxxx2 range has an operating temperature range -220C to +220 and the PYxxx6 range is -220C to +600C.
- Page 3 DETAILS OF MI CABLE The MI cable is insulated with magnesium oxide (M O) which is hygroscopic. To function correctly the cable should remain sealed at all times. Any ingress of moisture will lower the insulation resistance. The standard cold seal provides a sealed connection from the MI cable cores to the flexible PVC insulated conductors.
- Page 4 HANDLING PRECAUTIONS Do not bend the cable excessively. Especially avoid bending the cable near the end termination. (Refer to sub-section 4.4 below.) Ensure the cold seal junction and connecting wires are not heated above 105C. INSTALLATION Mount the transducer by clamping the body or using the step made by the larger diameter "flange"...
- Page 5 ELECTRICAL CONNECTIONS Front Coil GREEN Rear Coil BLACK The transducer can be energised by constant voltage or constant current (10mA) at a frequency of 2.4 to 5.0 kHz. When used with the 615 instrument, the bridge is completed within the instrument.
- Page 6 OPERATION Target The target range should cover the front face area of the transducer used, e.g. on a PY256C, the target size should be at least 25mm in diameter. The target thickness and size can affect the transducer sensitivity by a few percent.
- Page 7 ENVIRONMENT Temperature The `2' version PY has a working temperature range of -220C (-365F) to +220C (+390F). The `6' version PY has a working temperature range of -220C (365F) to +600C (+1110F). In each case the survival temperature is considerably higher. Radiation The PYs can withstand nuclear radiation to a total dosage of:- `2' version PY...
