Temperature-independent turgor pressure measurement device, method for producing said measurement device, and a method for temperature compensation for said measurement device
The invention relates to a clamp element (6) for a temperature-independent turgor pressure measurement device for measuring the turgor pressure in a plant sample, said clamp element comprising: a sensor-receiving portion (5) with a first contact surface, a surface lying opposite said contact surface, and a peripheral surface which connects the two, the clamp element having a longitudinal axis perpendicular to said first contact surface, and with a recess which is on the side of, and opening towards, said first contact surface a first force element which is arranged on the sensor-receiving portion surface that lies opposite the first contact surface a pressure sensor (4), arranged on a printed circuit board/lead frame, to measure a pressure response signal of the plant sample, said circuit board/lead frame being arranged with the pressure sensor in the recess of the sensor-receiving portion such that the pressure sensor faces the first contact surface and the circuit board/lead frame lies at the bottom of the recess said recess being filled with a cured potting material (12, 13, 14) such that this filling lies flush with the first contact surface, in a uniform manner and the clamp element or the measurement signal of the clamp element as a whole being compensated for temperature.
