Pressure signal collection structure

The utility model provides a pressure signal collection structure relates to and measures technical field. It includes the casing, and the casing upper end is equipped with the sensor storehouse, and sensor storehouse below is equipped with labyrinth type channel, and labyrinth type channel looks sideways at " bow " by a plurality of longitudinal channel and interconnection connection and appears, labyrinth type channel upper end and sensor storehouse intercommunication, the lower extreme communicates outward with the casing. The utility model provides an among the prior art pressure sensor polluted by the particulate matter to cause the unsafe technical problem of signal acquisition. The utility model discloses beneficial effect does: effectively prevent the particulate matter to pollute pressure sensor, ensure that pressure sensor can last effectual work for a long time, has reduced use cost. Pressure signal is stable, puies forward the high pressure sensor signal sample accuracy. Reduce pressure sensor and
