Page 13: Applications
Chapter 2 Applications Introduction The RUSKA 2416 may be employed as a null detector/indicator in the following manner: Gas-to-Gas The instrument may be used with dry air, nitrogen, carbon dioxide, some hydrocarbons, and the noble gases, but not with gases containing free hydrogen or oxygen. Although oxygen will not directly attack the materials of the lower cavity, there is the danger that an accidentally perforated diaphragm will permit the oxygen to enter the upper cavity. - Page 14 RUSKA 2413, 2417 & 2416 Users Manual Whenever a liquid is used in either side of the transducer, an open tube manometer must be connected in such a way that the pressure across the diaphragm may be adjusted to zero and that the meter may also be adjusted to indicate zero. In a liquid-to-liquid system, two manometers must be used —...

Page 15: Preparation For Use
Chapter 3 Preparation for Use Preparation for Use Normally, when a transducer is shipped from the factory, it has been calibrated with nitrogen and is dry in both cavities. Before installation, a quick performance tests may be made by first connecting the box to the cell, with power on, adjusting the sensitivity to maximum and the meter to zero. -

RUSKA 2413, 2417 & 2416 Users Manual is no valve on the line to the cell, the line must be temporarily disconnected and stopped off. The valve to the liquid supply reservoir is opened and the plunger advanced somewhat to remove the backlash in the pump spindle nut. With the reservoir valve closed, the screw crank is slowly rotated until the Bourdon gage pointer is observed to move a perceptible amount. -
Page 17: Operation
Chapter 4 Operation Operating Instructions In comparing the pressure of one system to that of another, it must first be established that the comparator or indicating device is adjusted correctly. The adjustment must assure the operator that all hydraulic and pneumatic heads have been accounted. With the transducer connected between two systems and prepared for operation, the power is turned on and the circuit allowed to warm up for ten minutes. - Page 18 RUSKA 2413, 2417 & 2416 Users Manual signal will not appear on the meter until the gas pressure is within 2 psi of the liquid, since this figure is the limiting value of the indicated differential pressure. Some liquid must be withdrawn from the differential pressure cell, allowing the diaphragm to move toward the center of the cavity whereupon the meter signal will approach the zero.

Page 19: Performance Observations
Chapter 5 Performance Observations Actual Sensitivity versus Apparent Sensitivity Although the differential pressure indicator is regarded as a null-indicating instrument, the degree to which a true null may be achieved depends upon the readability of the error signal displayed on the meter. In order to obtain a readable error signal, the diaphragm must move. -
Page 20: Detecting Leaks
RUSKA 2413, 2417 & 2416 Users Manual change in the sample volume, and the error will not be corrected by an adjustment of the pressure in the amount indicated by a pressure correction curve. A calibrating procedure in which the diaphragm presumably can be restored to its isostatic position by a physical adjustment of the electrical sensing-indicating circuit has been adopted. -
Page 21: Maintenance
Chapter 6 Maintenance Servicing the Instrument Failure of the instrument may result from a malfunction of the following components: Diaphragm Differential Transformer Electrical Feed-Thrus Connecting Cable Electronic Circuit Diaphragm In most instances, failure of the transducer has been traced to perforations in the diaphragm caused by particle contamination of the fluids. -
Page 22: Ruska 2413 Differential Pressure Null Indicator -Replacement Of Differential Transformer
RUSKA 2413, 2417 & 2416 Users Manual RUSKA 2413 Differential Pressure Null Indicator — Replacement of Differential Transformer A serious effort has been directed toward the construction of a differential transformer which is capable of continuous operation at high ambient pressures. Notwithstanding a thorough inspection and performance test at the factory, a transformer occasionally breaks down under the severe conditions within the cell. -
Page 23: Ruska 2417 Transducer - Replacement Of Differential Transformer
At maximum sensitivity, it should be possible to pin the meter from zero by pushing against the fitting; this is a very rough quantitative test. RUSKA 2417 Transducer — Replacement of Differential Transformer A serious effort has been directed toward the construction of a differential transformer that is capable of continuous operation at high ambient pressures. -
Page 24: Failure Diagnoses
RUSKA 2413, 2417 & 2416 Users Manual Failure Diagnoses Some transformers have been known to fail at high pressure and to resume operation at a lower one. Failure is usually traced to an opening in one of the windings. If an instrument fails to display a difference in pressure as expected, a simple and quick test will indicate if the cause is in the electronic circuit or in the differential transformer. - Page 25 Maintenance RUSKA 2413 — Replacement of Transformer 3. The feed-thru wires are very brittle and must be treated with the greatest care. Do not bend these short stubs when exchanging the transformer connecting wires. While using a 25-watt pencil type soldering iron, lift the transformer connecting wires from the feed-thru wires.

Page 33: General Information
Chapter 8 General Information Introduction This instrument employs contemporary time-proved analog techniques. The components were chosen for their long-term stability and reliability. Numerous test points exist on the circuit board that facilitate trouble-shooting, when necessary. The operational amplifiers are plug-in, which allows for easy installation. The 15-volt DC system is powered by a modular power supply which is, in turn, fully isolated from line voltages through a dual primary input isolation transformer. - Page 34 RUSKA 2413, 2417 & 2416 Users Manual...

Page 35: Functional Circuit Description
Chapter 9 Functional Circuit Description Introduction The excitation signal to the primary coils of the LVDT is generated by an oscillator made of Z2A and Z2B. The output of the oscillator (at TP7) is a 24 volt peak-to-peak sinusoid at a frequency of 5.1 KHz. This signal is attenuated by R5 and R6 and buffered through Z1B. - Page 36 RUSKA 2413, 2417 & 2416 Users Manual...

Chapter 10 Test Procedure Introduction Reference to Drawing Nos. 2416-60-200 and 2416-63 is recommended. A DC voltmeter with .001 volt resolution is sufficient for the single required potentiometric adjustment. For trouble-shooting, an oscilloscope will be required. All measurements are made with respect to TEST POINT 2 (TP2). - Page 38 RUSKA 2413, 2417 & 2416 Users Manual c.

Page 39: A Explanation Of Test Report
Appendix A Explanation of Test Report Explanation of Test Report When the RUSKA Differential Pressure Null Transducer is operated at an elevated pressure, the body is in a state of temporary strain. Even though the pressure on each side of the diaphragm may be equal, as they are when the two cavities are connected together, the output display meter indicates that a difference in pressure does exist. - Page 40 RUSKA 2413, 2417 & 2416 Users Manual U-tube manometer is connected to the appropriate side and the pressure required to restore the original null is measured. This figure is characteristic of the diaphragm and, in some instances, is small enough to allow indiscriminate overranges. The sensitivity at maximum gain is obtained by measuring the differential pressure required to sweep the meter pointer across the scale several times in a stepping fashion.
