  • Available with I.D.'s from .004" to .032" depending on the model
  • Used in a gauge to restrict the flow of rapidly increasing and decreasing pressures, reducing the immediate effect of pulsations and pressure spikes

Recalibrators & Adjustable Pointers

  • This option gives the user the capability of resetting the pointer by an adjustment screw accessible through the dial, or by a gear located on the pointer

Overpressure Protection

  • Overpressure protection of 3 times up to 10 times of the dial range is available on some models as a production option

Ammonia Refrigeration Gauges

  • Available in some gauge sizes, with pressure ranges of 0 psi to 5 psi, 0 psi to 15 psi and 0 psi to 30 psi

Receiver Gauges

  • 3 psi to 15 psi receiver gauges are available some gauge sizes/brands (316 stainless steel)

Metric Dials And Customized Special Dials

  • Dual scale metric dials in psi/bar, psi/kPa and psi/kg/cm2 are available on many models
  • Certain other scales are available for specific sizes and ranges, such as single scale bar and kPa, refrigerant scales and altitude scales
  • Customized special dials such as non-standard metric scale, tons of ram, lbs. of force, etc. are available in small quantities

Certified Calibration

  • Available on all of our gauge models
  • Certified Calibration provides the user with a serial numbered gauge along with a calibration sheet against a primary pressure standard
  • Traceable to the National Institute of Standards and Technology

Swivel Adaptor

  • Temperature ratings: 15,000 psi @ 200 °F and 3,000 psi @ 1,000 °F
  • Used with gauges and gauge valves to adjust the line of sight
  • Rotates 360° to allow the connected instrument to be positioned in the desired direction
  • The pressure connection is achieved with a tapered cone style compression fitting simply by tightening the swivel hex nut
  • All 316 stainless steel construction
  • Standard with 1/2" NPT male process – 1/2" NPT female instrument connections
  • Also available with 1/4" NPT connections, same specifications apply

Pigtail Steam Syphons

Pressure Snubbers

  • Piston-Type Snubbers
    • Resist clogging and are self-cleaning
    • Five different sized pistons included with each snubber to ensure the correct amount of snubbing for virtually every application
    • Available in brass and 316 stainless steel in 1/4" NPT, 1/2" NPT or SAE J1926-3: 7/16-20

Diaphragm Seals

  • Standard, Elevated Pressure, Non-Metallic, Lower Bolted and Replaceable diaphragm seal types
    • Designed to isolate the pressure measuring instrument from high temperatures, or corrosive or viscous process media
    • Can be used for remote mounting of pressure instrument(s) with capillary
    • Utilizes a replaceable diaphragm clamped between the flanged metal housings with an O-ring seal to create a leak-free union
    • Process connection sizes from 1/4" NPT through 1-1/2" NPT
    • Flushing port connection is an available option that allows the wetted areas of the seal to be cleaned, or the process vented without removing the unit from the line
    • Consider instrument size, pressure range, media composition, ambient and operating temperature, and maximum working pressure when selecting
    • Capillaries and cooling elements are available for elevated process temperatures
    • Fill fluid must be compatible with process media; i.e. Glycerin may become volatile in conjunction with a strong oxidizing agent such as chlorine, forms of oxygen or peroxide and nitric acids

Magnetic Spring Contact Switch

  • An excellent choice when an accurate pressure switch is required in addition to a reliable pressure gauge
  • Fully adjustable by the user
  • These switches are actuated by the pressure gauge pointer to provide accurate field adjustment
  • A removable adjustment key makes them tamper-proof
  • They operate with an extremely broad power supply, AC or DC up to 250V max. (30W 50 VA), allowing them to be used virtually anywhere in the world in addition to very remote applications with only DC battery pack power available
  • Standard units consist of (2) two magnetic spring switches; either one or both switches may be used:
    • Switch (1) one is normally closed
    • Switch (2) two is normally open with operation referenced on clockwise pointer motion
  • Magnetic spring contact switches are available as a factory installed option on 40-400 Series, 40-410 Series, 40-901 Series dry and 40-911 Series dry
  • The lowest full scale pressure range this switch may be used on is 0 psi to 60 psi because of the increased load on the pointer and Bourdon tube
  • A mating 4-pin connector with 5' of 4-wire and color coded shielded cable is standard
