The miniature Preset Flow Control is ideal for many applications involving pneumatic systems, including the control of cylinder speed.
The operation of the flow control is based on the movement of a small disc. The flat surface on one side of the orificed disc seals and permits flow through the orifice. The amount of flow permitted in the reverse direction is determined by the orifice size. In the forward direction full flow is permitted. The flow controls design allows a maximum supply pressure of 75 PSI with a minimum cracking pressure of less than 10” H2O. Orifice sizes are available from .004” to .040”. |

The EL-PRESS series digital electronic Pressure Meters and Controllers have a well-proven compact thru-flow design and are available in pressure ranges from 2-100 mbar up to 8-400 bar, both in absolute and relative (gauge) pressure. A differential pressure transducer can also be supplied in the ranges of 2-100 mbar up to 0,3-15 bar. The pressure controller performs with high accuracy and repeatability and should be specified for forward or backward pressure control. Todays EL-PRESS series are equipped with a diaphragm type piezoresistive pressure sensor and a digital pc-board as standard and offer high accuracy, stability and reliability. The basic digital pc-board contains all of the general functions needed for measurement and control. In addition to the standard RS232 output, the instruments also offer analog I/O. As an option, an integrated interface board provides DeviceNet, PROFIBUS-DP, Modbus-RTU or
FLOW-BUS protocols. |

The gas pressure regulators (RTP) are designed to reduce natural gas pressure from medium to low one, and to keep the gas pressure rate independent on input pressure and flow changes. The regulators are suitable for domestic as well as for industrial installations.
Description
Single stage
Single stage gas pressure regulators have diaphragm - spring single stage pressure regulator with the lever system control element.
Double stage
Double-stage gas pressure regulators have two stages of pressure reduction, both with diaphragm-spring control.
The RTP gas pressure regulators are equipped with the following safety devices:
* The over-pressure and under-pressure shut-off
* The relief valve

Press Man is a simple but yet efficient controller for maintaing constant pressure in heating and ventilation environments. It is charactized by a very robust construction and extremely simple user interface.
Press Man controls the HVAC pressure from an pressure transmitter with an analog output mounted directly in the ventilation system. Difference pressures can be obtained by incorporating mecanical blends etc. IP54 grade and integrated keys / display makes Press Man well suited for many applications.
Press Man has a setpoint, which is controlled by the arrows. A single press will put the setpoint one up or down, holding the arrows will make the setting change fast while pressed. Measured pressure will be displayed pr. 5 sec after keys have been released
Press Man has two relay outputs, the first is used on ON/OFF by the key setting, the other is used for alarming. ON/OFF is activated as the key is activated, the alarm output will be active when the output can not be reached whithin 30 minutes !. Means, that if the output internally is UNDER or OVER the MIN/MAX settings, the relay will activate. Flashing LO or HIGH in display
Press Man can indicate the real output for the attached speed controller, OR, it can indicate the real input from the attached pressure transmitter. Both values will indicate in percentage (0-100) of input and output)
Press man can be 100% stopped, pressing the ON/OFF button. Display will indicate OFF and the DC output will be forced to 0, as will be the 2 relays. Press man has individual settings for minimum and maximum speed for the attached speed controller. Settings to be controlled by MIN/MAX buttons. Parameters for Proportional Band and Integration Time is done from the keypads as any other parameter. The PI regulator will meassure the pressure, compare it to the setpoint and try to maintain the dc output to make the real pressure as close to the setpoint as possible. |
