In addition to strengthening an existing portion of the vehicle’s safety structure to further protect the battery pack in a severe side collision and adding a tamper-resistant bracket to the top of the battery coolant reservoir to help prevent potential coolant overfill, a sensor is also part of the solution. The added sensor in the reservoir of the battery coolant system monitors coolant levels to warn the owner if a problem develops.

The XT-1000 series offers a line of robust, stainless steel sensors with highly accurate continuous level measurement in lengths from 8 inches to over 13 feet. The XT-1000 measures liquid media levels using the complete probe length and is largely unaffected by temperature. The sensor offers constant sensing of fluid level regardless of the physical state of the media including: bubbles, foam, condensation, precipitation, pressure, temperature or changes in density.

The use of magnetostriction is ideal in applications that require extremely accurate indication such as the chemical and water treatment industries. The 4-20mA sensor is compatible with a variety of tank dimensions and offers an explosion-proof version for installation in potentially explosive atmospheres where electrical equipment of category 1 (zone 0) or category ½ (zone 0/1) are required. Also available with the digital Hart protocol operating system, the sensor is able to output the position of the first, second or both floats.

“The XT-1000 increases the breadth of the Gems continuous level product line with a highly accurate magnetostrictive technology solution” says Kevin Castonguay, Product Marketing Manager for Gems Sensors & Controls. “The high resolution sensor is a robust solution for a wide variety of OEM and end user applications such as; chemicals and petrochemicals, biotech and pharmaceuticals, mechanical engineering, water treatment, beverage, food processing and underground storage tanks for leak detection.”

High frequency (MHz) capacitive spectrum profiling technology enables the sensor to ignore foam and deposit build-up and differentiate between residue and actual product in a tank.

The solution involves sweeping the frequency band of 50 to 200 MHz for the capacitive sensor and taking three measuring points: electromagnetic field damping, permittivity phase shift of the molecule polarization in the magnetic field, and the media conductivity in the electric field. An algorithm in the sensor processes these measurements to calculate the signal amplitude.

The LSI series incorporates a unique, flexure-supported torque balancing system, which is rugged enough to withstand shock inputs of 1500 g, yet still provides excellent accuracy and repeatability over a wide operating temperature range. For added durability, sensor components and associated electronics are contained within IP64 environmentally sealed housing. Units are available in ranges of ±14.5°, ±30° and ±90°, and offer a high level, 5-Volt analog DC-output signal, proportional to sine of the angle of tilt. LSI series models are fully self-contained, and are able to connect to a DC power source and a readout or control device, to form a complete operating system. These robust units are ideal for use in civil engineering, structural monitoring, geophysical and seismic studies, machinery and structural alignment, pipeline leveling, crane safety and satellite antenna leveling applications, among others. Recommended accessories include bi-polar power supplies and the new DTI series digital panel indicator, which allows a user to read outputs directly in degrees.

The NASA-developed magnetic measuring system also has potential use in planes, trains and automobiles.

Originally developed by NASA to retrofit aging aircraft with safety equipment, the technology is a spinoff for designing and using sensors without the shortcomings of many commonly-used liquid storage measurement systems.

Traditional marine fuel-gauge float systems can provide inaccurate readings because of a boat’s movement. A vessel’s pitch and roll in open waters can create a “seesaw” effect on fuel gauges. This new wireless fluid-level measurement system has two stationary pieces of conducting material located in the fuel, connected to an inductor on the outside of the tank.

Another aspect of the wireless fuel-level sensor system is the design can be modified to detect water, a concern for recreational boaters. It also can be modified to detect other non-fuel liquid contaminants in a tank. While this particular system is for a marine application, it could be modified for other uses.

The new PRX+1660 series represents a new product line for the company, which enables Hermetic to address the need for reliable, robust, and reasonably priced sensors for liquid level monitoring applications in appliance, automotive, control, household, industrial, municipal, petrochemical, power generation, processing, and recreational markets.

These sensors can be used for level sensing or monitoring of brake fluid, contained water, dilute acid, gasoline, oil, or any number of process liquids, limited only by the series’ material of construction (polyamide or polypropylene).

As with all Hermetic Switch reed-switch-based designs, these sensors require no electric power to function since they operate using a permanent magnet-in this case, designed into the level sensor-so the sensors are not dependent on batteries and thereby can be used in extreme and/or remote environments for an extended period of time. Both “normally open” and “normally closed” designs are available in the new PRX+1660 series.

These PRX+1660 sensors can be mounted at the top or bottom of a liquid container or tank, depending on the application’s requirements. When operated within rated electrical loads, these float sensors will provide millions of cycles, long life, and years of reliable operation.

The rated power of the PRX+1660 series is 10 watts and the initial resistance is 0.30 ohms. Other characteristics include:

o Voltage Rating (V DC Max) – from 180 to 200
o Current Rating (A DC Max) – from 0.7 to 1.0
o Voltage Holdoff (V DC Min) – 200 to 240
o Operating Distance (inch) – 0.177 to 0.728 (4.5 to 18.5 mm)

Pricing for PRX+1660 series products ranges from $4 to $5 USD per unit, depending on the specific model and quantity. Hermetic Switch possesses the ability and desire to custom build solutions for specific applications.
