A C C E S S O R I E SMANUAL PRESSURE CONTROL PACKSThe Manual Pressure Control Pack provides a means of setting andfine tuning gas pressure, and vacuum, in a closed system. Typically, aManual Pressure Control Pack is used to control pressure to both apressure standard, which may be a gas piston (deadweight) gauge ora digital pressure indicator, and the device under test. The Pressure
Control Pack allows the operator to introduce the gas pressure froma source, such as a nitrogen bottle or air supply, using a cutoff andmetering valve. Once the pressure is near the desired set-point, theoperator can use the Precise Pressure Adjustor which is integrated
into the Pressure Control Pack to fine tune the pressure to the actual
set-point. The Precise Pressure Adjustor has a minimum sensitivity of0.00025 psi. The sensitivity improves as system volume increases.
In deadweight gauge applications, the Manual Pressure Control
Pack is designed to conveniently generate pressures in the gauge,absolute and true negative gauge (vacuum) mode of operation. Prior
to this design, significant changes were required to convert fromgauge to negative gauge mode of operation. Now, with the simple
turn of one valve, the Manual Pressure Control Pack is configured toallow negative gauge mode calibrations to be performed without
any changes to the system.
Two Manual Pressure Control Packs are available: the 2465-800
which is can be used to adjust pressures from absolute up to 1000
psi and the 2470-800 for absolute pressure to 3000 psi. Bothmodels provide a convenient reference gauge to provide a roughindication of the system pressure.
All pneumatic connections (1/4” NPT female) are located on theback of the unit allowing a compact and neat installation. The userneed only connect a gas pressure source and if vacuum measurements are required, a vacuum pump.
PRECISE PRESSURE ADJUSTORSThe Series 3800 Precise Pressure Adjustors provide the ability tofine tune the pressure in a closed system to a minimum of 0.00025
psi. These pressure adjustors are typically used to complement
existing equipment that is capable of roughly setting the pressure,and then using the Series 3800 to finely tune the pressure.
The system pressure is applied to two large chambers separated byan adjustable piston. A valve located on the pressure adjustor isclosed separating the two chambers, and adjustment is achieved byrotating the large knob which applies micrometer precise movement
to the piston. By moving the piston, the volume of the test systemchanges, therefore changing the pressure by a very small amountper turn. When the next pressure step is required, the operator
simply opens the valve on the pressure adjustor and using existing
equipment roughs into the next point and then repeats the processof closing the valve and setting the precise pressure.
Three different Precise Pressure Adjustors are available withpressure ranges to 1000 psi, 3000 psi and 10,000 psi. An optional
mounting bracket is available for mounting the Precise Pressure
Adjustor to a table top.

VACUUM PUMPS
Ruska also provides vacuum pumps as an accessory to ourproducts. Two models are offered, one with a capacity of 139 liters/
minute and another with a capacity of 69 liters/minute. Both pumps
include an auto-vent valve to vent the vacuum on power loss andprevent the oil from contaminating the instruments attached to thepump, a backstream filter to prevent molecular migration of oil during
normal operation, and a muffler for quiet operation. A 1/4 in. NPT
female fitting is provided in addition to a KF16 vacuum connection.
VACUUM GAUGEThe Model 99700 Vacuum Gauge is used to measure the vacuum ina contained system. It is typically used to allow zeroing of theModel 7010 Digital Pressure Controller, or to monitor the vacuum inthe bell jar of the Model 2465 Gas Piston Gauge when not using theModel 2455 Deadweight Gauge Monitor or Autofloat configurations,which have their own built-in vacuum sensing systems.

HAND PUMPSRuska hand operated pumps are positive displacement pumps thatfeature ease-of-use and long life. There are two basic models
available, each with a variety of configurations to meet the customers
specific needs. The Model 2426 provides precise pressure generation
and adjustment to 15,000 psi whereas the Model 2427 is capable ofgenerating pressures up to 40,000 psi.
Both the Model 2426 and 2427 can be provided in a variety of configurations. For example, the Model 2426 (pictured left) includes not only thepump, but also a dial indicating reference gauge, a 100 cc reservoir torecharge the pump when fluid is lost or compressed, and three highpressure cutoff valves. Please refer to ordering information on the backpage for a complete description of the various configurations available.

Hand Pump with accessories

Additionally, the Model 2426 Hand Pump can be used in a highpressure gas system for fine tuning the system pressure.
CONNECTOR BLOCKS
Ruska Connector Blocks provide a convenient means of connecting
the device under test into the system. The Model 2405 is rated to15,000 psi and is available in a variety of configurations along withmodels for hydraulic or gas service. The Model 2424 is available forhigh pressure systems to 40,000 psi.
Connector Blocks
MANOMETERS
Open tube reference manometers in hydraulic systems provide apoint in the system which can be opened to atmosphere, thereby
eliminating any unknown pressure bias and providing a reproduciblereference level for the device under test. They are commonly used inconjunction with the Ruska Model 2413 Differential Pressure Null
Indicator (see separate brochure), where a multimedia calibration
system is required. The Model 2409 is available for system pressures up to 15,000 psi. Otherwise, the Model 2421 should be usedwhich is rated for system pressures to 40,000 psi.
FILTER TRAPS
A filter trap is recommended in hydraulic systems to isolate thedevice under test from the calibrator, and therefore preventing
possible contaminants in the device under test from damaging aprecision calibrator, such as a deadweight gauge. The Model 2414 isavailable for pressures to 15,000 psi and the Model 2436 Filter Trap
is available for high pressure systems up to 40,000 psi.

Reference Manometers

RESERVOIRSThe 1500 cc capacity of the Model 2419 Reservoir provides aconvenient storage of hydraulic fluid that must be added to thesystem to replace fluid lost during the calibration process. Thestandard reservoir has a Lucite tank with a stainless steel bottom.
Other reservoirs are available depending on the fluid type.

Pressure Intensifier with Control Manifold

PRESSURE INTENSIFIER AND MONITOR
The Model 2440 Pressure Intensifier is typically used in oil to gas
deadweight gauge systems and provides a means to boost standard
air or nitrogen bottle pressure to as high as 15,000 psi. The unit isdesigned for mounting under the bench top of a multimedia(typically oil to gas) deadweight gauge system utilizing the Model
2413 Differential Pressure Null Indicator. The non-lubricatedcompression cylinder eliminates contamination and provides a small
volume of high pressure gas suitable for most requirements. The
simplicity of operation and long life make the Model 2440 an
excellent choice for oil to high pressure gas calibration systems.
The Model 2444 Pressure Monitor is recommended for use with thePressure Intensifier to provide the operator with a rough indicationof the output pressure. The Pressure Monitor incorporates a dial
indicating gauge to 15,000 psi and a vent valve for returning toatmosphere or for a downward calibration run.
