Monitor’s two-year warranty stands behind every TrueCap sensor.
TrueCap® RF capacitance sensors offer cost-effective point level monitoring with reliability you can count on. Monitor’s complete line, which features models MK-2 and MK-2e, provides you with the most affordable solution for your application. Monitor’s RF capacitance probes are designed to provide a high level of sensitivity, stability and durability for powder and bulk solids applications, as well as liquid and slurry applications.
Monitor offers the market an unmatched selection of RF Capacitance point level sensors. Several factors should be considered when selecting the proper TrueCap® RF capacitance point level sensor.
Ease of Calibration
MK-2 : Extraordinary convenience of push-button calibration, sensitivity and self-test.
MK-2e : Simple 2-step manual calibration
MK-2 : Automatically adjusts its calibration to account for temperature changes providing maximum reliability.
It is important that the calibration of a probe remains stable during swings in the process and ambient temperatures.
Changing Contents / Characteristics
MK-2 : Push-button re-calibration and an available remote calibration module.
MK-2e : TrueCap sensors can be calibrated to the material with the lowest dielectric constant (usually the driest material) in order to sense all products which could enter the bin.
Heavy Materials & Tight Areas
Some applications require compact, sturdy probes for heavy materials or confined spaces. The MK-2 and MK-2e offer a stub probe for extra durability for heavy products and a compact design for tight areas. Both models also use heavy duty 3/8 inch (9.5 mm) diameter probes.
All TrueCap sensors can sense solid materials, but be careful to also look at all application parameters.
Many liquids, slurries and sticky bulk solids tend to cling to probes. Product build-up immunity through a driven shield design is a must. The MK-2 and MK-2e provide product build-up immunity and can typically be used with these materials.
When locating sensors near vibrators, bin dischargers or other vibrating equipment, the split architecture version is recommended.
Universal Power Supply
Minimizing the number of variations can maximize value for OEMs and product resellers. The MK-2 is the only TrueCap sensor that provides this capability. NEED FOR VISUAL INDICATION Both the MK-2 and the MK-2e are provided with a high intensity LED indicator on the housing (Ordinary location integral sensors only).
The MK-2 and MK-2e are available approved for Class I and Class II hazardous locations. See “Specifications” for details.
For applications up to 450°F, (232°C) the MK-2 and MK-2e offer stainless steel mounting connections which act as thermal barriers and a split architecture version which completely removes the electronics from the process.
Large particles can leave air gaps which could lead to inaccurate readings. However, smaller particles and fines usually fill in the gaps.
