Mid-West Model 127 Piston Type Differential Pressure OEM Indicator, 25 – 100 PSID

ABLE Instruments are Mid-West Instrument’s Official Representative for Sales and Service in the UK and Ireland, including the Model 127 Piston Type Differential Pressure OEM Indicator (0-25 to 0-100 PSID or equivalent). The Model 127 from Mid-West Instrument is an affordable and reliable OEM piston type indicator, designed for applications requiring differential pressure measurement. With a full-scale accuracy of ±5% and a differential pressure range of 0-25 PSID to 0-100 PSID, the Model 127 is suitable for a wide variety of uses. Despite its budget-friendly price, this model delivers exceptional performance, making it an excellent choice for installations that are indoors or within weather-protected enclosures.

Key features of the Model 127 include a rugged piston-type sensing element that ensures durability and accuracy. The device is built to resist corrosion and includes a shatter-resistant lens for enhanced durability. Over-range protection safeguards the gauge from high-over-low and low-over-high pressure spikes, contributing to its reliable operation. The Model 127 comes with a one-year warranty, underscoring its quality and the manufacturer’s confidence in its longevity.

The gauge is available in a compact dial size, with oval, single-side, or dual-side configurations measuring 1-1/4” x 2-1/4”. It maintains a differential full-scale ascending accuracy of ±5%, adhering to ASME B40.1 Grade D standards. Capable of withstanding working pressures up to 3000 PSIG (207 Bar) and operational temperatures from -40°F to +200°F (-40°C to +93°C), the Model 127 is robust and versatile. Constructed with high-quality materials, including aluminium or 316 stainless steel for the body and 316 stainless steel pistons and ceramic magnets for internal wetted parts, this model ensures high performance and durability.
