- Safety and Reliability
McDaniel Controls, Inc., designs and manufactures its gauges to minimize failure
and to protect personnel and property. The use of laminated safety glass, rather
than plexiglass or singlestrength glass, prevents dangerous pressure build-up in the
case; the glass breaks at pressures that vary with the glass diameter. The brittle
glass cracks uniformly and the laminate glass won't craze or discolor in service.
- Easy Repair
If any McDaniel gauge requires repair, down-time can be minimal because all
McDaniel gauges are field-repairable, quickly and easily, with only a screwdriver
needed for disassembly.
If circumstances permit and factory repair is preferred, we will make that repair
at a nominal service charge. See Warranty and Repair for further details.
- Pulse Vibration Protection
McDaniels offers liquid-filled gauges for applications involving vibration or
pulsation. Glycerin is an excellent damper of Bourdon tube movement. Emersion
of the entire measuring assembly in a protective liquid envelope provides
lubrication and shuts out corrosive or dirty atmospheres - thereby minimizing wear
of moving parts and prolonging gauge life significantly.
- Choice of Filling
When you order a McDaniel Filled Gauge you may choose to fill it yourself or you
may order it factory filled with the liquid of your choice. Thus, you can maximize
inventory utility and minimize inventory cost.
Glycerin filling has a lower operating temperature limit of 32 DEGF undiluted. The
mixture of distilled water in proportions up to 35% will lower the limit
commensurately, to -40 DEGF.
Silicone can extend the lower temperature limit to -60 DEGF. The maximum
temperature limit is not determined by the fluid but by the gauge's synthetic case
seal. At elevated temperatures the seal may bake and loose its elasticity.
Warning: Glycerin filled gauges should not be used in applications involving strong
oxidizing agents such as chlorine, nitric acid or hydrogen peroxide.
- Warranty and Repair
We warrant our pressure gauges to be free of defects in material and
Replacementof any defective gauge will be made at no cost to the purchaser. We
will repair any of our gauges which has malfunctioned for a cost of $15.00 on 4"
and larger sizes; $7.50 on 2-1/2" and smaller. Prices are F.O.B. Paradis,
