WINTERS

WINTERS is a brand of pressure and temperature instrumentation with a long history in industrial measurement. The line includes pressure gauges, thermometers, thermowells, and differential pressure instruments used across process, sanitary, and general industrial applications. WINTERS products are commonly specified where a mechanical, dial-type reading is required and where the instrument must match a particular connection, range, and accuracy class. The brand's catalog covers a broad set of gauge families, including the PSQ sanitary series, the PFQ panel-mount series, and the PFD differential series, along with tire pressure gauges and other specialty instruments. 3G Electric supplies the WINTERS line to buyers who need to match existing installations or specify new ones. The product range includes dial sizes from 2 inches to 4 inches and larger, pressure ranges from vacuum through low positive pressures up to several thousand psi, and accuracy classes such as ±1.5%, ±1.50%, and ±2.5% of span. Connection types include 1/4 in NPT male, 1/2 in NPT, Tri-Clamp sanitary fittings, and barbed connections for low-pressure differential service. Wetted parts vary by series: brass and bronze for general-purpose gauges, 304 stainless steel for sanitary and corrosive-service models, and diaphragm or capsule sensors for low-pressure and differential applications. Case materials include steel, 304 stainless steel, and nylon, with lens options such as polycarbonate. Several models carry IP ratings, including IP54 for the PFD differential series, indicating protection against dust and water splashes. Sanitary gauges in the PSQ series are 3-A certified, making them suitable for hygienic processes where cleanability and material compatibility are required. Many WINTERS gauges are available with options such as pressure relief valves, protective boots, mounting brackets, and calibration certificates. The PFD series includes a certificate of calibration as a standard item, and panel-mount gauges may be field-fillable for vibration resistance. 3G Electric supports the WINTERS line by maintaining stock across common ranges and configurations, providing specification assistance to match dial size, connection, range, and accuracy to the application, and supplying the accessories and mounting hardware that accompany these instruments. For buyers working with existing WINTERS installations, 3G Electric can help identify equivalent or replacement part numbers based on the original specifications. The brand's instruments are used in applications ranging from automotive tire pressure checks to sanitary process lines in food, beverage, and pharmaceutical production, to panel-mounted indication on OEM equipment and skids. Because WINTERS offers multiple series with overlapping ranges but different materials and connection types, selection typically depends on the process fluid, required accuracy, environmental conditions, and the mounting interface. 3G Electric's role is to make that selection straightforward by presenting the relevant specifications and ensuring the supplied instrument matches the requirement.

Frequently asked questions

Common questions about WINTERS from 3G Electric.

What is the difference between the WINTERS PSQ sanitary gauge and a standard WINTERS pressure gauge?

The WINTERS PSQ series is a 3-A certified sanitary pressure gauge designed for hygienic applications. It uses a 304 stainless steel case, polycarbonate lens, and stainless steel wetted parts, and connects via a 1 1/2 in Tri-Clamp fitting. Standard WINTERS gauges, such as the PFQ panel-mount series, typically use brass or bronze wetted parts and NPT threaded connections. The PSQ series is available in ranges such as 0-30 psi, 0-60 psi, 0-100 psi, and 0-200 psi, all with ±1.50% accuracy and a 2 1/2 in dial. Selection depends on whether the process requires clean-in-place compatibility and sanitary fittings.

What accuracy classes are available in WINTERS pressure gauges?

WINTERS pressure gauges are offered in several accuracy classes depending on the series. The PSQ sanitary series carries ±1.50% accuracy. The PFQ panel-mount series includes models with ±2.5% and ±1.5% accuracy. The PFD differential pressure series uses a diaphragm sensor and is intended for low operating pressure differentials. Accuracy is specified as a percentage of span, so the actual permissible error depends on the selected range. When ordering, confirm the accuracy class required for the application, as it affects both the gauge mechanism and the calibration certificate that may accompany the instrument.

What connection types do WINTERS gauges use?

WINTERS gauges are available with several connection types. Common options include 1/4 in NPT male, 1/2 in NPT, 1 1/2 in Tri-Clamp for sanitary service, and 3/16 in barbed male for low-pressure differential gauges. Panel-mount models may have center back or bottom connections. The connection type must match the mating fitting or adapter in the installation. For sanitary applications, the Tri-Clamp connection allows quick disassembly for cleaning. For general industrial use, NPT threaded connections are typical. When replacing an existing gauge, verify the connection size, type, and location (bottom, center back, or lower mount) to ensure compatibility.

Are WINTERS differential pressure gauges suitable for low-pressure applications?

The WINTERS PFD series is designed for low operating pressure differentials. It uses a diaphragm sensor and a nylon housing with a 2 1/16 in dial and a 3/16 in barbed male connection. The PFD series carries an IP54 rating, indicating protection against dust and water splashes. A mounting bracket with screws and a certificate of calibration are included. This series is typically used to monitor filter status, flow indication, or other low differential pressure measurements where a mechanical dial gauge is preferred. The maximum operating pressure and differential range should be confirmed against the specific model selected.

What materials are used in WINTERS gauge wetted parts?

Wetted parts materials vary by WINTERS series. General-purpose panel-mount gauges, such as the PFQ series, use brass and bronze wetted parts. Sanitary gauges in the PSQ series use stainless steel wetted parts, with a 304 stainless steel case. The PFD differential series uses a diaphragm sensor, with the wetted materials dependent on the diaphragm and housing construction. The choice of wetted material depends on the process fluid and its compatibility with brass, bronze, or stainless steel. For corrosive or hygienic processes, stainless steel wetted parts are typically specified. Always verify chemical compatibility between the process fluid and the wetted materials before installation.

Can WINTERS panel-mount gauges be filled for vibration resistance?

Some WINTERS panel-mount gauges are field-fillable, meaning they can be filled with a damping fluid after installation to reduce the effects of vibration and pulsation. The PFQ series front-flange panel-mount vacuum gauge, for example, is described as field-fillable. This feature allows the user to add glycerin or silicone fluid as needed for the application. Field-fillable gauges are useful in environments where vibration is present but the exact damping requirement is not known at the time of purchase. If a gauge is not field-fillable, it may be available in a liquid-filled version from the factory. Confirm the specific model's fill capability before ordering.
