Ammonia Gauges

McDaniel Controls Ammonia GaugesFor industrial and commercial ammonia refrigeration applications.
McDaniel designs and manufactures its industrial and commercial ammonia refrigeration gauges to minimize failure and to protect personnel and property. A laminated safety glass lens is standard on all ammonia gauges (optional on models K9, E9, or G9). The use of a laminated safety glass lens, rather than plastic, provides additional safety, and will not scratch, craze, or discolor.
Ammonia gauges are offered in dial sizes 21⁄2 inch (63mm), 4 inch (100mm), 41⁄2 inch (130mm), and 6 inch (160mm) in all case configurations.

1/2″ NPT, 1/4″ NPT & 1/8″ NPT available

Glo-Gauge

McDaniel Controls Glo GaugesDesigned for greater visibility in the light of day or in the darkness of night.
The McDaniel Safe Zone Reflective Glo-Gauge™ with easy-view operating range markers was designed to allow anyone viewing the pressure gauge the ability to easily determine and judge if operating conditions have become abnormal.
Anyone can easily customize each “safe operating zone” simply by setting tabs located outside the gauge lens face. These tabs are given green retro-reflective enhancements and allow many different types of operating pressure zones to be indicated. Minimum and maximum limits can be indicated and set apart at acceptable and safe operating pressures; or, all the way apart for more relaxed operating zones, depending upon each application – On the spot customization!
This remarkably easy solution permits anyone viewing the gauge, up close in the light of day; or far away in lowlight conditions, to easily see if the process is operating in the “Safe Zone” as set during gauge installation. (A valuable benefit for out-of-the-way gauges up on catwalks, pipelines, and in contaminated areas, etc.)

1/2″ NPT & 1/4″ NPT available

Plant Safety Gauge

McDaniel Controls Plant Safety Gauges

  • Solid front/full blowout back.
  • Blowout back hinged to reduce the risk of becoming a projectile, causing personal injury or damage to equipment.
  • Accuracy specification is 1/2 of 1% full scale pressure (ASME B40.1 grade 2A)
  • Over range of 130% full scale pressure without loss of accuracy.
  • Design over range of 300% full scale pressure without rupture of Bourdon tube.
  • All wetted parts (tube and socket) are annealed for stress relief to minimize bourdon tube failure possibilities.
  • Spiral bourdon tube, which has an effective working radius of over 1000 degrees is used on pressure ranges 800 psi and above to reduce work hardening and/or fatigue usually caused by pressure pulsation due to severe service.
  • Over range and vacuum limits included internally as a standard safety feature.
  • Pointer stop on dial located at the 6 o’clock position to further reduce a possibility of a false indication.
  • All threads (1/4″ and 1/2″ NPT) are manufactured using the best method available. The threads are rolled, for the purpose of reducing galling that can be an issue in most installation applications.
