Mid-West Instrument Diaphragm/Bellows - type Differential Pressure Gauge/Switch 105-106 | |

Mid-West Instrument Model 105-106 DP Gauge |

| The Model 105/106 diaphragm/bellows design provides a simple, compact,accurate, direct-acting, low range differential pressure indicator.
The major components of the Model 105/106 are a two-piece body, a multiple diaphragm/bellowssensing element and over-pressure assembly, atorque tube assembly, a range spring and the gaugefront assembly.The body halves provide the pressure containmentfunction.They also clamp the sensing element andover-pressure assembly between the halves,isolating the high side and low side pressures of the system.The high side body half also provides a mount for the torque tube assembly and the gaugefront assembly.The sensing element is exposed to the differentialpressure and deflects in response to the differentialpressure.This assembly incorporates a bi-directional relief valve which provides over-pressureprotection in both directions.When over-pressuredfrom the high side, the valve is opened by amechanical stop as the sensing element deflects toits maximum travel.When over-pressured from thelow side, the spring-loaded valve opens when the differential pressure exceeds it's maximum rating.The opening of the valve in either direction equalizes the pressure and protects the unit. A range spring is provided to adust the spring rate of the system to suit the various differential pressure ranges of the instrument.
The torque tube assembly consists of arigid shaft and torque tube.The torque tubeis welded to a bushing which is fixed to the high side pressure body half.The other endof the tube is welded to the shaft.The shaft is connected to the sensing element by a linkage.As the sensing element deflects, it causes the torque tube to twist.The torquetube provides a frictionless transmission ofan output which is proportional to the differential pressure.
The torque tube shaft extends into thegauge front assembly and is connected to allow-friction, jeweled movement which provides output to the pointer.
If your application requires switching in addition to localindication, our all solid state "Locked Logic" system is the mostaccurate available.With no moving cams, levers, etc.it doesnot affect the accuracy of the gauge on which it is installed.Switch accuracy is the same as the gauge accuracy.
Visible set pointers are provided, adjustable to within 5% of fullscale of each other.The set points are adjustable from 5 to 95% of full scale. Internal adjustment is standard.

| Features:
-
Working pressures of 500, 1500, 3000, or6000 psig (400 bar) are available in the samehousing size.The gauges are cost efficient,light weight and easy to install.
-
Aluminum, Brass, Carbon Steel, or 316Stainless Steel housings with a choice ofCopper-Alloy or Stainless Steel diaphragm/bellows and a wide variety of elastomers.
-
The materials of construction can easily be matched to the application.
-
Mechanical over-range protection high to lowand low to high.The Models 105/106 gaugesrequire no additional “fill”liquid in their over-range system, eliminating the possibility of system contamination.
-
.The gauge is easierand less expensive to service/repair than competitive units.
-
Uni-directional or bi-directional dials are readilyavailable.Offers the ability to read positive or positive/negative differential pressure with one gauge.
-
Gauges are optionally available with one or two switches.Offers the ability to have alarm or control.
-
The Models 105/106 come with a five year limited warranty
