Do not remove the Hall probe from its original package until you are ready to install it. Ground yourself to discharge any static electric charge that may build up in your body while working on installation or handling the probe. Handle the probe by its edges or by the leads to avoid touching the uncovered electrical system of the probe. Do not touch a measured sample by an uncovered type of the Hall probe.

 

To avoid damaging the probe by frozen water, the surface must be carefully dried by fine airflow before insertion to a cryostat. Cool down the probe slowly in dry atmosphere. After the measurements dry up the probe using the stream of dry gas at maximum temperature of 40 °C.

 

Maximum ratings are absolute ratings. Exceeding any one of these values may cause irreversible damage to the Hall probe. Before connecting the Hall probe to a current source check the output for a current peak when it is turned on/off. The bias current must be switched off during rapid temperature changes (cooling and heating) of the sensor. Do not switch on maximal bias current unless the sensor is at a constant temperature.

 

The offset voltage of the Hall probe can be changed if some component of your cryogenic system has a remanent magnetic field. In this case, it is recommended to carefully examine the equipment for magnetic materials or parts, which tend to remain magnetized.

 

Our Hall probes are not intended for use in life support equipment and systems. Use of the sensor in such applications requires the advance written approval of the AREPOC Ltd. Certain applications using this probe may involve potential risks of personal injury, property damage, or loss of life. In order to minimize these risks, the customer to minimize inherent or procedural hazards should provide adequate design and operating safeguards. Inclusion the probe in such applications is understood to be fully at the risk of the customer.
