A fluid sensor comprises a sensor housing (12), a sensor package (14), an actuator (16) and a switch (18). The sensor package (14) is disposed within the sensor housing (12) and includes first and second screens and at least one sensing membrane. The sensing membrane is disposed between the first and second screens (36) and is adapted to expand when exposed to a predetermined quantity of a first predetermined fluid. The actuator (16) is disposed proximate the sensor package (14) within the sensor housing (12) and moveable between a first position and a second position through an intermediate position. The switch (18) is disposed proximate the actuator (16) and is operable between closed and open positions. When the actuator (16) is in the second position at least a portion of the actuator (16) depresses the switch (18) to control an-electrical, circuit connected therewith.

The invention discloses an antenna channel testing method based on 6-port circuit, and the technical problem object to resolve is to simply, quickly and reliably judge the state of the electronic label read / write device antenna. The method of the invention includes the following steps: the baseband processor setting the carrier frequency output by the phase-locked loop, switching-on the power amplifier, starting up A / D conversion chip, sampling the signals, sending constant length of code to the frequency mixer; the detector diode circuit modulating signals from the micro-strip lines, sending to the baseband processor for processing after difference amplification and D / A conversion, so as to judge the antenna state. Compared with the prior technology, the baseband processor of the invention sets up the carrier frequency output by the phase-locked loop; the frequency mixer modulates a section of constant length code onto the carrier produced by the phase-locked loop and outputs after power amplification; the detector diode circuit checks out the modulating signals from the micro-strip lines, the modulating signals are formed into digit signals after amplification and D / A conversion, and then are sent to the baseband processor for processing to judge the antenna state, which is simple, quick and reliable.
