2510/2610

2" Diaphragm-Type Pressure Indicator

9100 Image

Application

Rochester diaphragm-type pressure indicators are designed for durability under a wide range of severe operating conditions. They have proved their reliability and accuracy for over 40 years by indicating pressures of air, engine oil, fuel, transmission oil, etc. for engines, pumps, compressors, portable generators, hydraulically-operated machinery, and many other demanding applications where other types of indicators fail in short periods of time.

General Information & Features

The key element in these pressure indicators is a metal diaphragm staked and soldered to the case. A rigid stop plate reinforces the diaphragm to help prevent calibration changes or damage to over pressurization or exceptional shock and/or vibration.

The internal components are housed in a black-painted, terneplate-steel case with a glass lens retained by a stainless-steel bezel crimped to the case and sealed with a resilient gasket.

See below for other information on standard construction and other available options at extra cost.

Data Sheet

General Specifications*

Mounting

Model 2510 - clamp mounted
Model 2610 - direct mounted

Accuracy

±10% of indicated points on the scale

Sensitivity

Pointer action is virtually frictionless. Following pressure changes smoothly and positively.

Endurance

For 50% dial span, over 500,000 cycles. For smaller pressure cycle spans, indefinite life can be expected on most applications.

Overpressure

Normally 100% of indicated scale range.

Temperature

Not damaged when complete assembly is exposed to temperature of -50°F to 250°F, -45°C to 120°C.

Adverse Environment

Lens and bezel are sealed against rain, ice, sand and dust.

Shock

Will withstand up to 10 G's shock without damage.

Vibration

Suitable for continuous duty under 2 G's, vibration up to 100Hz.

Pulsation

Will tolerate severe pulsation under which other types are likely to fail. (Pulsation dampeners available)
