摘要： A fluid (oil) storage tank is often in a remote place. A temperature sensor strip is affixed vertically down the outside of the tank. Each sensor sends its electronic signature and temperature to a local microprocessor. Various types of computations yield an accurate level indication on a local display, all powered by a car battery, solar panel or power supply. Data can be sent remotely as well. For explosive environments only a small processor is powered adjacent the tank. Then a second processor has the power to compute and analyze the raw temperature data and display it at a safe distance from the tank with only a twisted pair of low volt wires reaching the tank. Other non-explosive tanks such as a water tank can use a signal processor adjacent the strip for all data collection, computing and display functions.

摘要： A method of measuring a level of liquid cryogen, comprising the steps of immersing a liquid cryogen level probe in a liquid cryogen, applying a propagation current to the heater (26) to induce quench in at least an adjacent part of the superconductive material (22); removing the propagation current from the heater; applying a measurement current to the superconductive material; and measuring (30) a voltage across the superconductive material thereby to determine the level of the liquid cryogen. In articular, the method comprises the steps of monitoring (40) the voltage across the superconductive material while the propagation current is being applied; and ceasing application of the propagation current in response to the detection of a voltage across the superconductive material which exceeds a certain threshold level.

摘要： A detector and a method for determining the presence of a fluid are disclosed. The detector comprises a probe having a thermistor with the probe being arranged to be exposed to a fluid and to allow thermal flow between the thermistor and the fluid, a temperature sensor for measuring the temperature of the thermistor and a controller. The controller is arranged to supply electrical power to the thermistor when it is below a predetermined temperature to heat it up and to turn off the supply of electrical power to the thermistor when it is at or above the predetermined temperature. The presence or identity of a fluid exposed to the probe is determined based on the proportion of time that power is supplied to the thermistor to maintain it substantially at the predetermined temperature. The ambient temperature of the fluid to which the probe is exposed may also be measured and electrical power may be supplied to the thermistor to keep it substantially at a predetermined temperature above the measured ambient temperature.

摘要： An oil level sensor for detecting an oil level is arranged in an engine oil pan. The oil level sensor includes a mounting section and a sensing section. An air hole is formed at an upper end of a cover member of the sensing section. The air hole is surrounded by a tubular portion of a shield member attached to a baffle plate of the oil pan. Therefore, any splashed engine oil in the oil pan is restricted from entering the cover member of the sensing section through the air hole. Also, a clearance (α) for venting air is formed between the tubular portion and the baffle plate.
