This utility model discloses an anti-clogging dust sampler sampling rod device, belonging to the technical field of sampling equipment. It includes a dust sampler, a connecting pipe, a first mounting plate, a second mounting plate, and a chamber. One end of the dust sampler is fixedly connected to the first side of the first mounting plate. A threaded sleeve is fixedly installed on the second side of the first mounting plate, with the first and second sides of the first mounting plate facing each other. Both ends of the connecting pipe are fixedly connected to the third side of the second mounting plate and one end of the chamber, respectively. A threaded rod is movably installed on the fourth side of the second mounting plate, with the third and fourth sides of the second mounting plate facing each other. The threaded rod and the threaded sleeve are threadedly engaged. A rotatable toothed ring is installed on the surface of the connecting pipe, and a rotatable gear is installed on the third side of the second mounting plate. The gear meshes with the toothed ring, and the gear is fixedly connected to the threaded rod via a connecting rod, so that the rotation of the toothed ring drives the threaded rod to rotate synchronously through the gear. This structure balances assembly / disassembly speed with secure connection, meeting the requirements for continuous environmental monitoring.

A kind of TMR sensor assembly for detecting urea tank liquid level, including PCB substrate and TMR magnetic control IC arranged on PCB substrate, patch resistance, one end of PCB substrate is provided with blank and narrower connecting end, and connecting end is electrically connected with corresponding connector crimping terminal in connector plastic shell by multiple connecting wires.The utility model has the advantages of smaller size, smaller gear interval can be set, higher resolution compared with traditional dry reed sensor, its life is much longer than the switch life of dry reed, and reliability is greatly improved.

The utility model relates to new energy automobile electric control technical field discloses a kind of relays with sampling function, including shell and the static contact point of being set to the outside of shell, the inside of shell is extended with mounting contact point to static contact point, integrally setting on mounting contact point is the sampling contact point for obtaining sampling signal on static contact point, sampling contact point is electrically connected with the sampling harness for transmitting sampling signal, sampling harness extends to the outside of shell, a kind of relay with sampling function of the utility model, by setting sampling terminal and sampling harness in the shell inside of relay, the redundant harness of relay outside can be effectively reduced, to simplify the harness arrangement in BDU, to improve the heat dissipation performance of relay. By integrally setting sampling contact point on mounting contact point, both the connection stability of sampling contact point and static contact point can be improved, and sampling accuracy can be improved, while avoiding the sampling error caused by unreliable installation.
