Mechanical pressure gauges have been around for more than 160 years.  They are a reliable measurement instrument and very cost effective.  They are used to measure pressures from vacuum up to thousands of psi.

 

Mechanical pressure gauges are used in a variety of applications from light commercial to heavy industrial.  Some applications have extreme temperatures, some have corrosive media and some have high vibration.  The problem with vibration is it makes it difficult to read the gauge and adds stress as well as wear and tear to the gauge mechanism, thus reducing its life span.

 

To counter the effects of vibration, the pressure gauge case historically has been filled with a high-viscosity liquid, which creates a “molasses” effect and absorbs the vibration, resulting in a stable pointer and pressure indication.  Common fill liquids include glycerin and silicone.

 

StabiliZR Pressure Gauge In Action

 

Unfortunately, there is a downside to liquid-filling pressure gauges.  the liquid may leak while the gauge is on the shelf, during transport or in the field, creating a mess and possibly a safety hazard.  Another disadvantage is discoloration of the liquid when exposed to UV light or high heat, which makes the gauge difficult to read.  Liquid filling also limits the operating temperature range of the gauge, thus limiting its application in cold and hot temperatures.

 

Winters Instruments has developed a new technology which creates a stabilizing effect, but without filling the gauge with liquid.  How?  A dampening compound is applied directly to the pointer movement only, as opposed to the complete case, thus greatly reducing the quantity of liquid required and the resulting overall weight.  The compound is contained in a large sealed chamber which avoids evaporation and maintains lubrication to the pointer movement for the life of the gauge.  This new dampening system is called StabiliZR™ and it is available in Winters’ most popular liquid-filled pressure gauges.  StabiliZR™ is identified with a ZR designation at the end of each series name (ie: PFQ-ZR, PFP-ZR, PPC-ZR and PN2-ZR).

Winters’ new StabiliZR™ technology has been submitted to severe-cycle and high-temperature testing with tremendous results.  After thousands of cycles and multiple hours of being exposed to high heat, the performance of Winters’ StabiliZR™ dampening movement remained optimal and the accuracy consistent.  This proves StabiliZR™ will thrive in heavy industrial applications where the ambient temperatures are high and where there is frequent cycling.

 

Technology is constantly evolving, even in a mechanical world where the same sensing mechanism has been used for almost two centuries.  Liquid filling of pressure gauges offers some protection against vibration, but the new dampening movement offers the same results with additional advantages.  It has proven to be reliable in the toughest of applications and is gaining more and more recognition throughout the engineering world.

 

The time has come to move from traditional liquid filling and its problems and embrace StabiliZR™, a modern optimal dampened system available only from Winters Instruments.
