Point Level Sensor uses Patented Technique To Provide Self-Diagnostics

Elburn, IL –It seems as though some of the lowest cost devices, such as a point level sensor used for detecting the high level status in a vessel, can cost you the biggest headache if it fails, not to mention clean up and lost production costs.  Monitor Technologies is pleased to announce that the SafePoint(R) point level sensor incorporates the patented use of Hall effect technology to continuously monitor it's status and ability to operate reliably.  If a fault condition is detected an independent relay changes state to indicate a failure condition.  No longer do you have to wait for a problem before learning of a sensor failure.  This can save you time and money.

The SafePoint level sensor is a fail-safe level sensor combining the proven aspects of rotary paddle technology and state-of-the-art Hall effect sensing to reliably detect the presence/absence of process material at the point of installation, as well as to detect electrical and mechanical failure modes that might keep the unit from operating properly.  The SafePoint is a relatively low cost fail-safe level sensor, about $300 US, with state-of-the-art electronics and patented technology to continuously monitor it's health status as well as the presence and absence of process material.  It is designed specifically for applications with powders and other bulk solids, can be provided with approvals for Class I and II hazardous areas and carries CSA (for North America) and ATEX certifications for these environments.

Monitor Technologies LLC is a leading supplier of level, flow, particle emission and aeration instrumentation for the worldwide powder and bulk solids market. The experience and market knowledge gained over five decades has earned Monitor a reputation for providing high quality and reliable product solutions.  Monitor is located in Elburn Illinois, give us a call today and let us put our creative solutions to work for you!



Spotlight: RF Capacitance Level Sensor

TrueCap® MK-2
Advanced RF Capacitance Level Probe

The TrueCap® Model MK-2 RF Capacitance point level probe is designed to provide a superior and stable sensitivity threshold making it suitable for a variety of powder / bulk solids and some liquid or slurry applications.

Advanced features of the Model MK-2 include:
> Automatic immunity to material build-up on the probe by its driven shield design
> Push-button calibration
> Enhanced temperature compensation
> Maximized reliability via smart sensing algorithms like “self-validating” fail-safe protection
> Visible status LED on ordinary location units
> Versatility through a variety of configuration options including: hazardous location version, split architecture design, quick-connect process connection, stub probe, cable extensions, solid extensions, Nylon® probes, Ryton® - equiv. probes, etc.

A practical application for the TrueCap would be to use this level sensor where a residual material build-up on a different sensor would cause a false material level indication.

Principle of Operation for the TrueCap RF Capacitance Level Probe:
The vessel wall and the active probe element establish an impedance reference between each other when exposed to air which has a dielectric constant of 1. When materials with a dielectric constant greater than 1 are in close proximity to the probe, the impedance of the sensing field between the sensor and the vessel wall will change. Once the amount of change exceeds a threshold that was electronically determined during the calibration process, an output relay will either be energized or de-energized depending upon the position of the fail-safe selector on the probe’s electronic circuit board. A change of as little as .5 pico-farad is all that is necessary for the probe to sense the presence of material.
