The present invention relates to an inorganic cohesion agent for self-compacting cement pastes consisting of a co-precipitated SiO2CaCO3 mixture. The pressure sensor forms an electrical switch for passing an activation signal to a EOSESD protection module in response to axial movement of the housing relative to the probe assembly. This transformation of the coating into a polysiloxane coating preferably ensues by a thermal treatment effected at temperatures of <100\xb0 C. The vertical pillar also includes a second vertical transfer device having a source region, a drain region, and a body region therebetween on a second side of the vertical pillar.
