    Abstract: PROBLEM TO BE SOLVED: To realize a low cost and therewith obtain a signal which resists the error of the introduction position of a water pressure and the interference of installation water depth and accurately corresponds to an effective earth pressure. SOLUTION: Filters 34, 35 are placed in an air gap 10 sandwiched by 2 pieces of rigid plates 13, 14 forced by the earth pressure, and therefore the water pressure is forced but a sand pressure is not forced. Accordingly, a load cell 41 having structure without the sensitivity to the water pressure detects only the effective earth pressure. A signal cable 51 can be passed through in the air gap 10 and then a plurality of pressure transducers 1, 2 can be effectively connected and also the signal cables 51, 52 can be inserted through the inside. Consequently, the distribution pressure in a depth direction can be accurately measured. In the point part, an insertion head 71 to make insertion into the earth easy is attached to a support body 23. A plurality of the pressure transducers 1, 2 are connected one after the other via a coupling support body 24, and also the coupling is made rigid by bridging a coupling plate 61.
