A flexible waveguide is a piece of high-quality dielectric, which ends with transitions to standard waveguides with flanges. For ease of operation, the waveguide is protected by an elastic shell. Basic properties Manufacturability of the connection; Small losses and VSWR; Economy. Operating conditions Operating temperature range from 5 to 50 ° C; The relative humidity of the air is up to 98% at a temperature of 25 ° C. Technical specifications Waveguide cross section, mm 3.6×1.8 Flange type according to GOST RV 51914-2002 Frequency range, GHz 53.57-78.33 VSWR 1.25 Losses, 2.5 dB Length, mm* 500

It is designed to prevent the flask from surfacing when it is thermostated in a laboratory bath or liquid thermostat.

The ZVpP-100 vacuum valve with pneumatic actuator equipped with 100mm conditional passages is designed to overlap vacuum systems in the pressure range from 1x10-6 to 1,07x105 Pa (from 0,75x10-8 to 800 mm Hg). The ZVpP-100 vacuum pneumatic shutter is manufactured in the climatic version of the UHL placement category 4 (i.e. for moderate and cold climate) according to GOST standard 15150-69. The working environment is air and non–aggressive gases. The temperature of the working environment is from plus 1°C to plus 40°C. The vacuum valve with a pneumatic actuator is not intended for use in fire and explosive hazardous industries. The ZVpP-100 vacuum pneumatic shutter consists of a mechanism, a housing and a pneumatic actuator. The pneumatic actuator includes a pneumatic cylinder, on the piston of which a permanent magnet is installed to determine its position by means of magnetic position sensors "Closed" and "Open" fixed on the cylinder body and a distributor into which compressed air is supplied through a fitting. The speed of the pneumatic cylinder in particular and the operation of the shutter as a whole are regulated by rotating the pneumatic throttle head, if the pneumatic throttle heads are fully tightened, then the speed of opening and closing the shutter will be maximum. The solenoid, powered by a connector, serves as a distributor control device and is applicable in standard production conditions where the relative humidity of the air is not higher than 75%.

It is designed to measure sound pressure in the air and is used in noise measuring equipment as a measuring transducer of infrasound, sound and ultrasonic pressure.

The body of the 25M URS valve is of welded construction and consists of a shell, a seat, side and lower nozzles. With the lower branch pipe, the 25M URS valve is connected to the vacuum system with studs. The smooth part of the stem serves as a visual indicator of the "open" or “closed” valve positions. The casing is designed to protect the valve from accidental openings, and also serves as additional protection against precipitation, sand, dust entering the inner cavity of the valve. The valve opens when the flywheel rotates counterclockwise. The valve closes when the flywheel rotates clockwise.

It is designed to prevent the flask from surfacing when it is thermostated in a laboratory bath or in a liquid thermostat.

To achieve the maximum sensitivity during measurements, a special prefix is used to the FT-801 Fourier spectrometer, which is an optical unit with a built-in highly sensitive MST detector cooled with liquid nitrogen. The set-top box is installed in the cuvette compartment of the spectrometer and connected to the corresponding external electrical port, the detector is turned on programmatically. In this case, the sensitivity of the method increases many times (up to 20) – depending on the type of standard uncooled detector in the spectrometer). The speed of recording spectra is also increasing. The operating time after filling the cryostat (200 ml capacity) with liquid nitrogen is at least 6 hours. Increasing the sensitivity of the spectrometer using a prefix with an MST detector may be required for many applications: in fiber spectroscopy, when recording emission spectra of low-power emitters, in trace gas analysis with high spectral resolution, when determining the presence of impurities in samples in ultra-low concentrations, when using multi-pass gas cuvettes, etc. In the picture: on the left in the cuvette compartment there is a capler with fiber from Art photonics GmbH, Berlin, Germany, on the right there is a prefix with an MST detector. Technical specifications The recommended number of scans when registering spectra is 16 Spectrum registration time at 50 scans (resolution 4 cm-1), sec 20 Cryostat capacity, 200 ml Working time after filling the cryostat, 6 hours Overall dimensions, mm 225×175×75 Weight, kg 1.45
