Explosion proof integrity: hazardous location certifications for critical plants

D20, D30 and D70 Series Industrial Diaphragm Seals

Winters diaphragm seals isolate pressure instruments from corrosive, viscous, and high-temperature process media. Threaded and flanged assemblies are constructed from Hastelloy, Monel, and titanium alloys. The units are filled with specialized fluids for thermal transmission.

Corrosion proof alloys: diaphragms made of AISI 316L, Hastelloy C-276, Monel, and tantalum
Design variations: welded, threaded replaceable, and ANSI/DIN flanged industrial seals
Thermal dissipation: cooling elements and flexible capillary tubing rated to +400°C
Operating ratings: working pressure endurance handling process pressures up to 400 bar

Bimetal Industrial Thermometers and Pt100 Temperature Probes

Winters industrial thermometers and Pt100 RTD sensors monitor thermal conditions along manufacturing piping. The TMT series features an Every-Angle adjustable housing enabling viewing from any angle. An external reset screw allows rapid zero calibration without dismantling.

Measuring ranges: industrial temperature scale coverage from -50°C to +500°C span
Adjustable housing: Every-Angle swivel dial design for flexible viewing orientations
Stem and thermowell lengths: immersion probes from 63 mm to 1000 mm in AISI 316L alloy
Electrical transmitters: integrated head transmitters providing calibrated 4-20 mA output

Needle Valves, Gauge Cocks and Manifold Valve Blocks

Winters installation hardware includes SNV needle valves, siphons, and multi-valve manifolds for secure instrument maintenance. The assemblies allow safe isolation and venting of impulse lines without plant shutdowns. Stainless steel provides durability against surges.

SNV needle valves: precise flow shut-off and throttling rated to 400 bar working pressure
Pigtail siphons: coiled and U-bend steam condensation loops protecting against thermal damage
Manifold valve blocks: 2-valve and 3-valve manifolds for instrument zeroing and calibration
Pulsation snubbers: porous metal and piston damping elements absorbing hydraulic shocks

Vibration Resistant Pressure Gauges PFQ-ZR with StabiliZR Movement

Winters PFQ-ZR pressure gauges feature the patented StabiliZR movement designed specifically for high vibration and mechanical pulsation applications. Unlike conventional liquid-filled gauges utilizing glycerin or silicone fluid, StabiliZR dry gauges employ an internal dampened pointer mechanism.

A specialized dampening capsule mounted on the pointer pinion dampens pointer flutter without filling the gauge housing with fluid. This completely prevents dial discoloration, fluid leaks during transport or maintenance, and potential process contamination.

The AISI 304 stainless steel housing with a bayonet bezel ring provides IP65 environmental protection, while lead-free brass or AISI 316L stainless steel wetted components endure working pressures up to 1000 bar.

Corrosion Resistant Stainless Steel Gauges PFP for Chemical Processing

Winters PFP series industrial pressure gauges are engineered for aggressive chemical, petrochemical, and refining operations where both measured process media and ambient air contain harsh compounds.

The bourdon tube sensing element, connection socket, and movement gears are manufactured from acid-resistant AISI 316L stainless alloy.

The socket-to-case joint on 63 mm, 100 mm, and 160 mm gauges is hermetically sealed via automated laser welding under inert gas shielding, ensuring leak-free performance across extreme process temperatures up to +400°C. The construction satisfies strict safety requirements with a solid front baffle wall and blowout back disc for plant personnel protection.

WinSMART Intelligent Pressure Transmitters with HART and Modbus Protocols

Winters WinSMART series smart pressure transmitters represent microprocessor-based measurement instruments designed for automated process control systems.

The primary sensor comprises a monocrystalline silicon piezoresistive element with excellent zero-point stability and active temperature compensation over full operating conditions.

WinSMART transmitters are available in gauge, absolute, and differential pressure configurations with a 100:1 turndown ratio. The base accuracy rating is 0.05% or 0.075% of calibrated span, delivering precision metrological monitoring for critical refining and power generation circuits.

Diaphragm Seals D20, D30 and D70 for Instrumentation Process Isolation

Winters D20, D30, and D70 series diaphragm seals provide reliable fluid isolation between pressure instrument sensing elements and hot, corrosive, viscous, or slurry-laden process streams.

The seal consists of two chambers separated by a flexible metallic diaphragm: the lower chamber contacts the flowing process fluid while the upper chamber connects to the instrument and is filled with an incompressible transmission fluid.

Typical filling fluids include silicone oils or synthetic high-temperature fluids. Diaphragms are fabricated from corrosion-resistant alloys including AISI 316L stainless steel, Hastelloy C-276, Monel 400, Grade 2 titanium, and pure tantalum.

Bimetal Industrial Thermometers TMT and Pt100 Temperature Elements

To monitor operating temperatures across industrial processing equipment, pipelines, and storage vessels, Winters Instruments manufactures a comprehensive line of mechanical and electrical temperature instruments.

TMT series industrial bimetal thermometers employ a helically wound bimetallic coil combining two metals with different thermal expansion rates, guaranteeing rapid and repeatable thermal response.

Gauges are produced in 75 mm, 100 mm, and 125 mm dial sizes inside an AISI 304 stainless steel housing sealed to IP66. The patented Every-Angle swivel union permits 360° dial rotation and 90° tilt for optimal viewing.

Gauge Audit Program G.A.P. and Field Engineering Maintenance Services

Winters Instruments offers the comprehensive Gauge Audit Program (G.A.P.) designed to optimize facility instrumentation reliability, improve plant safety, and lower replacement inventory costs.

Field specialists evaluate installed pressure gauges, transmitters, and thermometers across operating units, documenting operating parameters, tag numbers, and failed hardware.

The audit identifies misapplied instruments, vibration damage, and chemical corrosion, providing plant managers with an actionable engineering report and corrective replacement recommendations for continuous uptime.
