A method for manufacturing a pressure detecting unit for a measuring device for measuring a pressure status value of a plant specimen, the method comprising the following steps:
- mounting a sensor unit, configured to detect the pressure status value, at a mounting surface of a carrier substrate;
- fastening a frame to and on the mounting surface of the carrier substrate, the frame including a fastening surface, a contact surface oriented opposite the fastening surface, and an inner surface which defines an opening and extends between the fastening surface and the contact surface, the frame being situated at the carrier substrate in such a way that the fastening surface faces the carrier substrate, and the inner surface surrounds the sensor unit;
- and
- filling the opening of the frame with a filling material for forming an elastic pressure coupling layer.
