AF011B Microassembly
AF011B Microassembly
A high-speed signal limiter amplifier. Designed for use in electronic counting frequency meters. Description: The magnitude of the input signals for selecting the switch input and inverting the signal of the limiter amplifier at a supply voltage of ± 5 V: - logical "0" not more than 0.2 V; - logical "1" at least 4.8 V. The value of the input signals of switching on / off the switch at a supply voltage of ± 5 V: - logical "0" no more than 3.3 V; - logical "1" at least 4.1 V. The magnitude of the output signals of the switch at a supply voltage of ± 5 V and a load of 300 ohms connected to zero potential: - logical "0" from 3.1 V to 3.4 V; - logical "1" from 4.0 V to 4.3 V. The minimum input voltage of the sinusoidal shape in the frequency range from 10 Hz to 200 MHz should be no more than 30 mV. The maximum input voltage of the sinusoidal shape in the frequency range from 10 Hz to 200 MHz must be at least 1 V. The value of the supply voltage: - positive 5±0.2 V; - negative -5±0.2 V. The current consumption should be no more than: - from a positive power source 110 mA; - from a negative power supply 35 mA.

Crimp support rings (stainless steel) for sealing rings with high sealing capacity
Crimp support rings (stainless steel) for sealing rings with high sealing capacity
The ISO-KF connection (DIN 28 403 and ISO 2861) allows quick installation and replacement of components in vacuum systems. The connection consists of two symmetrical ISO-KF flanges (1), a centering ring with an O-ring seal (2) and a quick-release clamp (3). High-vacuum ISO-KF connections can be mounted without using a tool by simply turning the nut of the quick-release clamp.

SPEAKER SWITCHING DEVICES
SPEAKER SWITCHING DEVICES
To switch the nozzle columns, conventional taps (reverse purge, 6-, 8- and 10-port) are used, which, however, are not suitable for switching capillary columns. An alternative way to switch capillary columns is to change the flows in the capillary columns, which is produced by the so-called "Dins switches" (PD). TECHNICAL CHARACTERISTICS of PD The switching time setting range is from 0.1 to 999 min. Switching time is 0.1 s. The dead volume of the crane is less than 1 µl. The temperature of the tap is no more than 350 °C. The pressure in the crane line is not more than 0.4 MPa. Electric power supply — 5 V.

LIQUEFIED GAS METERING VALVE
LIQUEFIED GAS METERING VALVE
The metering valve for the analysis of liquefied gas (KDSG) is designed for the introduction of liquefied gas or other liquid under excessive pressure into the evaporator of the chromatograph. KDSG is a 4-way crane, in which a dose of a certain volume is installed. The tap is installed on the evaporator of the chromatograph. A dose of any volume can be installed on the tap. Dose change can be performed by the operator. The amount of the dose volume is indicated on the tag. Technical specifications The dose volume is from 0.25 to 4.0 µl (at the request of the consumer, the dose volume can be increased up to 10 µl). The tap temperature is no more than 150 °C. The pressure in the crane line is not more than 0.48 MPa. The angle of rotation of the crane handle is 90 °C.
