1036 in-line sanitary pressure gauge and 1037 sanitary instrument fitting virtually eliminate process deadleg. The design of the 1036 sanitary gauge and instrument fitting allows for the diaphragm of the gauge to be positioned at the gauge instrument fitting, eliminating the pocket or deadleg that may cause contamination. 

The 1036 sanitary gauge and 1037 instrument fitting utilize a 1.5″ Tri-Clover-type mating connection. This feature offers flexibility to use the 1036 with the 1037 instrument fitting on sanitary instrument fitting for tube sizes from .5″ thru 2″.

X1032 Xmitr Transmitter Sanitary Gauge

X1032 sanitary Xmitr™ combines the advantages of the proven pressure gauge with patented transducer technology to create a single, convenient, dual-function instrument.

The unique Xmitr™ incorporates traditional transmitter features including 4-20mA and voltage outputs while a local indication is provided on a 2½” or 3½” dial.

Measurement accuracy is rated at up to 1% BFSL in ranges through 1,000 psi and a choice of 1½” or 2” Tri-Clover® sanitary connections are offered.

(A ¼ NPT connection is also available on the non-sanitary models). With only half the number of instruments to install, the Xmitr™ reduces the cost of purchasing,

installing and calibrating multiple instruments:

Voltage and 4-20mA outputs
1% BFSL includes non-linearity, hysteresis and non-repeatability
Meets CE heavy industrial
Ranges: vacuum to 1,000 psi / 60 bar
Temperature performance of 0.25% per 10 K error typical
1½” or 2” Tri-Clover^® sanitary connections

IP65/NEMA 4 ingress protection available

Ashcroft Type 80 Iso-Ring

With the Ashcroft® isolation ring, the instrument is in contact with the fill fluid, not directly with the process flow. Clogging or fouling is never a problem. The Iso-Ring has a flexible inner cylinder, behind which is the fill fluid. As process liquid flows through the pipe, it exerts pressure.

The pressure exerted by the fill fluid is then monitored by the instrument-sensing element. A 360-degree flexible cylinder means no plugging, assuring reliable and accurate pressure readings. A built-in threaded needle valve is provided as standard. This permits the removal of a pressure instrument for calibration, repair, or replacement without shutting down the process flow.

Adaptable to a variety of process conditions and applications, the Ashcroft® Iso-Ring can be used for protection of instrumentation such as pressure gauges, switches, transmitters, recorders and transducers. The Iso-Ring fits between customer-supplied piping flanges like many butterfly valves, and is available for piping diameters from 2″ to 20″. It can be used at any pressure within the limitations of ASME classes 150 and 300, and even in most vacuum applications.

Ashcroft® Type 85 and 86 Iso-Spools are used for small-diameter piping. Designed to provide a large sensing area in the smaller pipe diameters from 1″ to 2″, the patented Iso-Spool is offered in either NPT threaded or flanged models. Type 86 is available with flat or raised-face flanges.

ASHCROFT® Type 1279 Duragauge® Pressure Gauge with Phenol Case VS Competitive Thermoplastic Case

Phenolic resins like those used in the case of the Ashcroft Type 1279 Duragauge® process gauge are the first commercially successful polymers.

Their balance of chemical and heat resistance made them a “wonder material” when developed. Ashcroft process gauge competitors use thermoplastics for their cases which are typically easier to mold than phenolic.

However, since process gauges are often exposed to applications requiring chemical and temperature resistance and thermal stability, the Type 1279 Duragauge process gauge with a phenolic case offers these and other superior features.

The Ashcroft Type 1279 case is made of PLENCO 02370, Black Phenolic Resin. It is a low ammonia, single stage curing phenolic resin. Phenolic resins are “thermosets” meaning they cure with temperature.

After curing, additional heating will not melt the material, but instead make it harder. If heated high enough, the materials will begin to degrade.

Typically, phenolic doesn’t burn, but instead will “char”, breaking down to form ash and giving off a little smoke. “Thermoplastics”, like Pocan (Polybutylene Terephthalate) on the other hand, will melt when exposed to heat. Lanxess, the manufacturer of Pocan, lists its melting point as 437°F.

Thermoplastics are also more likely to burn than thermosets. As such, they often incorporate flame retardants to prevent burning. When thermoplastics burn, the material will melt, creating a pool of burning liquid, or even worse, spattering burning molten plastic onto nearby surfaces.
