    A probe and sump drain assembly (128) includes a fitting (136) secured to the wall of a sump (98) to which a probe housing 146 is threadedly engaged. The fitting is provided with a stepped bore having larger (142) and smaller (140) diameter portions. Seals (154, 156) carried on the housing (146) control fluid communication through passages (160, 162) communicated with the larger portion (142). A ring terminal assembly (170) provides an electrical connection with the fitting (136) and with a transversely projecting portion (166) of the probe (144) regardless of the angular orientation of the portion (166) of the probe (144).

    and the lamp on the panel is off. When the water level reaches the part of the conductor 10 protruding from the sampler, the resistance will drop and the signal will work. Drainage of the sump is carried out by manipulating the bottom of the sampler 7 until the seal 18 moves away from part 12, while the seal 19 protects part 24 from ingress of water that flows through the radial channel 21 and axial channel 22 to the outside of the separator. The device has a transversely curved part 24, which interacts with a contact device, equipped with electrically conductive rings 28 and 29, mounted for rotation and contact with conductors 8 and 9., 5 hp, f-ly, 3 sludge.
    The invention relates to a combination of a desiccant dehumidifier and a sampling device for a separating device, and is particularly used to alert the operator of a transport facility when the level of water in the separator's clarifier is high / low.
    The purpose of the invention is to expand the functionality of the device.
    Figure 1 shows the device, a general view; figure 2 - sampler; FIG. 3 is a section A-A in FIG. 2. FIG.
    The device is connected to a separator to separate the immiscible components from the liquid mixture, for example, to separate the water and diesel fuel in the fuel supply system of a car with a diesel engine. The separator includes a housing 1, which is fixed, for example, to a car, and a replaceable separator cartridge 2, which is replaced at certain intervals. The housing 1. Is provided with an inlet pipe 3 and an outlet pipe 4 for connection in said fuel supply system.
    Between the pipes 3 and 4 there is a separator for separating water in the form of droplets from the fuel and for directing the droplets into the bowl-shaped lower part 5 forming the sump 6. The latter is equipped with a sampler 7 connected with conductors 8 and 9 with a copy and with a warning lamp on the dashboard of the vehicle so that
    show that sump 6 contains water and must be dried.
    The sampler 7 is made in the form of an electrically conductive probe with a tip 10, located in an elec
    a variable insulating body I1, made with a thread 12, which forms a threaded engagement with a nozzle 13 for attaching the sampler to the wall of the sump 6, which is made with part 14 of smaller diameter and part 15 of larger diameter. Thread 12 is pre-digged by drainage slots 16 and
    17 (FIG. 3), which extend axially along the threaded portion 15 to allow fluid to flow out.
    Insulating housing 11 contains
    axially spaced circumferential 0-shaped o-rings 18 and 19. The 0-shaped o-ring 18 is in engagement with part 14 of a smaller diameter of the sampler 7, and a larger diameter seal 19 is in part 15 with a larger diameter- Seals 18 and 19, the corresponding parts of the body 1 1 and sampler 7 form
    annular cavity 19. Radially extending channel 20. connects cavity 21 with axially extending. channel 22, which passes through the lower part of the housing 11. One end 23 of the corresponding end of the housing 11 is exposed to a fluid containing. the settler 6 ends in the sump 6, and the other end of the sampler 7 ends in the transversely protruding part 24. The sampler 7 also includes
    An intermediate part 25, which is bent around the radial channel 21 and the longitudinal channel 22 and is located at a distance from them towards the periphery. Pipe 26 connects conductors 8 and 9 to the sampler. This assembly includes a peripherally extending portion 27 that surrounds the sampler 7 and the housing I 1. Two axially spaced rings 28 and 29 are located in the peripheral annular portion 27 of the outlet assembly 26 and surround the housing 11. The ring 28 is intended to make electrical contact with the sampler 7, and a block of insulating material 30 isolates ring 28 from ring 29. The latter is connected to conductor 9 and makes electrical contact with transversely protruding part 24. Ring 29 is in electrical contact with transversely protruding Part 24 The device operates as follows. During operation, the inlet and outlet nozzles 3 and 4 of the separator are installed in an appropriate fluid supply system, for example a fuel supply system to a diesel engine of a transport vehicle. The liquid through the inlet 3 passes through the steam separator, where water separates and falls into a sump 6 in the form of droplets. The liquid component removed from the liquid mixture by the separator will gradually fill the sump 6. The latter is initially filled with a liquid mixture, while in the case of a mixture of fuel and water (water in very small quantities), there is a high total resistance between conductors 8 and 9. Accordingly, the indicated lamp on the panel (not shown) will not light up. However, when water is removed from the liquid mixture and fills sump 6, the resistance of the electrical circuit between the insulating body 11 and the sampler 7 decreases dramatically, and the water level reaches the protruding part of the conductor 10. When this happens, the lamp on the panel turns on through a normal control circuit (not shown), which is sensitive to changes in resistance. Accordingly, the vehicle operator is warned that the sump 6 should be drained. The drainage of the sump 6 is carried out
    A wort mounted inside the nozzle with the possibility of removal from it, made in the form of a measuring electrode, equipped with an insulating body, which is complete with a channel connecting it to the cavity of the sump, and equipped with a contact node that provides the connection of the electrode with an external electrical circuit, characterized in that in order to simplify the use of the device, the contact node BHnojnteH in the form of a housing, equipped with an additional electrode and mounted between the electrodes with the possibility of rotation of the contact device Niemi, wherein one end of the measuring electrode is mounted in the sump, and the second is arranged horizontally and is connected with the contact device.
    2. The device of claim 1, wherein the contact is 74 by unscrewing the case I1 from the sampler 7, until the 0-shaped annular seal 18 moves away from part 14 of smaller diameter to part 15 of the larger diameter of the latter. When this happens, water from the sump 6 flows into the peripheral cavity 21. The 0-shaped O-ring seal 19 protects the connection between the transversely extending portion 24 of the probe from water ingress. Water in the cavity 21 flows through the radial cape 20 and the axial channel 22 to the outside of the separator. From time to time, the separator medium loses efficiency and must be replaced. Accordingly, the cartridge 2 must be removed from the housing 1 and replaced with a new one. The removal of the cartridge is accomplished by screwing the housing 11 from the sampler 7 so that the sampler assembly is completely removed. The nozzle assembly 26 is held on the housing of the sampler 7 and is removed with it. The entire cartridge 2 is then removed and a new cartridge 2 is installed. The housing 1I and the nozzle assembly 26 are then mounted on the sampler 7 with a new cartridge.
