MASS make Diaphragm Sealed Pressure Gauges are designed to measure the corrosive fluids pressure, where suitable material for bourden tube is not available.

The Diaphragm assembly withstand various corrosive actions encountered and seals the Bourdon tube from the process fluid. The displacement of the liquid filled in the Bourdon tube, through movement of the diaphragm, transmits the process pressure to the gauge. The Diaphragm sealed connections are available with threaded type, flanged type and capillary type mountings.

ifferent type of Chemical Seals can be provided such as :

Flange-type diaphragm seals Cell-type (sandwich) diaphragm seals Flange-type seals with extended diaphragm With hygienic-type connection- SMS standard- Tri clamp fitting Pulp and paper industry design High pressure diaphragm seals, homogeniger flange Welded body, male thread Capsule-Type Chemical Seals

MASS make Utility Pressure Gauges are available in 40, 50, 63, 80, 100, 150 & 250mm dial size. These are specially designed for valve positioners, airfilters & regulators, small boilers, fire extinguishers, pharmaceutical & food processing equipments, pumps, compressors, hydraulic & pneumatic systems, ammonia & refrigeration services. Quality Control features carried out on each gauge. Leak test -Overload test - Calibration and Accuracy test - Hyteresischeck -Thread check by ring gauges - Visual Inspection of finishing of internal components, dial printing, paint of dial & casing, entire assembly of gauge & final packing for shipment.

MASS' make thermowells are design to protect the temperature gauges from various corrosive media, Pressure, Viscous material or Velocity and abrasive's. A thermowell design permits quick removal and easy fitment of thermometer for replacement, repair and testing.

'MASS' thermowell features welding neck or screwed connection from solid bar construction to fit standard stem length. 'MASS' can give thermowells in straight, tapered, stepped and standard flange construction. 'MASS' make thermowells are widely used for Bi-metal, Mercury, Gas filled thermometer, sensors and different application like Pulp and Paper industries, Food and Beverage industries, Machine and Apparatus construction, Chemicals, Petrochemicals, Fertilizers, Refineries, Pharmaceuticals and National Thermal Power Stations.

'MASS' make mercury filled temperature gauges are made of a sensor bulb, transmitting capillary and a special flat bourdon tube, which are pressure-filled with mercury. As temperature changes the bulb will change the pressure in the system and indicated on the scale, calibrated in temperature units. A Bi-metal device is connected to the bourdon tube to compensate for temperature error due to variation in ambient temperature. Mercury filled temperature gauges measures from 38C to 600C with an accuracy class of+1% of full scale. 'MASS' make mercury filled gauges are economical, rugged, reliable and accurate measuring instruments available in different dial sizes, connection, mounting with different type of capillary with different length (maximum up to 25m). Mercury filled temperature gauges are also available with accessories like Antivibration spring, Electrical contact, Gauges with Glycerin or Silicon oil filled and with thermowells.

MASS make Master Gauges are designed for use as a reference gauge for recalibrating general service gauges, transmitters and other pressure operated instruments.

These gauges are easy to carry for field use and for spot inspections. To make reading easier and faster each pressure gauge is provided with readble dial. Reading error caused by paralax is eliminated by aligning the knife edge tip pointer with its reflection in the mirror band on the gauge.

MASS Make SingleDouble Snap action Magnetic Eletrical Contact Gauges are available in 100mm & 150mm dial size. These gauges serve for the measurment and control of pressure by switching 'on and off electrical equipments. Thus eliminates the need of separate switches for equipments such as pumps, motors, turbines, blowers for audiovisual alarms for signalling irregularities. These Contacts may be used under almost all operating conditions, they are largely immune to vibration. The contact pin carrier of the indicator is equipped with an adiustable magnet which attracts the contact arm just prior to reaching the indicator. This prevents arcing and burning of contact pins.

The pressure element of these instruments has two S.S.316 bellows, balance mounted. The value shown on the dial is the difference between two input pressure or depressions coming in to each bellow. 'MASS' Differential Pressure Gauges are entirely made of S.S.316 wetted parts, therefore they offer the same corrosion resistance (inside and outside) as the Bourdon Pressure Gauges. Moreover the mechanical resistance of the bellows allows important one-sided overpressure, compare to the differential pressure (up to 20 times in some cases).

All differential pressure gauges are used for measurements of flow, level, filter clogging, pressure drop measurement, air conditioner & chemical processor.

Optional Features :

Adjustable micrometer pointer Window Plexiglass or safety glass Anti vibrations filling liquids. Glycerin or silicone oil. Oil free manometric parts for oxygen service. Special threaded or flanged connection. Other dial graduations: linear, square root, flow, level, '0' at center. Electric contacts. Diaphragm seals of different materials.

Diaphragm gauges are suitable for measuring pressure of all kind of fluid and gaseous medium. The measuring element is a sensitive corrugated diaphragm fixed between two flanges. For slurry and viscous liquids flanged connections can also be incorporated. Low Pressure Bellow Capsule Gauge are designed for non-corrosive and non-aggresive application.

These Gauges have bellow capsule which is composed of two corrugated metal discs of Brass / Stainless Steel joined by brazing / argon arc welding. A rise pressure will cause the corrugated Capsule / Diaphragms to expand and this motion is transferred to the indicator through sector, pinion movement mechanism. A similar type of low pressure built-in capsule gauge can also be offered having almost similar kind of mechanism.

Provides Extra Margin of Protection from Vibration and Pulsation. 'MASS1 make Glycerine Filled Pressure Gauges are installed on Powerpacks, Hydraulic Machinery, Pumps, Compressors, Power Plants, Pipelines and Transmission Stations where Vibration & Pulsation are destructive factors. Glycerine filling makes the difference, the movement is submerged and constantly lubricated. The damaging effect of pulsation and vibration are minimised Pointer flutter is virtually eliminated because both the liquid filling and a restrictor screw in the Socket help in dampening pulsation.
