Design features of the d-MPBX involves a stiff hermetically sealed and potted central core that includes all of the electronics. The anchors are a simple aluminum tube to which are attached extension springs that positively attach the anchor to the borehole wall. The inherently digital nature of the signals eliminates the necessity for expensive analog-to-digital conversion and results in low cost readout unit that reads data directly in real world units (mm and °C). The signals themselves are robust and can be transmitted over 500m of lead-wire. If broken the lead-wire can be twisted and taped together. The sensor output is an ASCII (9600,8,N,1) digital signal which can be read by a low cost readout unit (d-Reader), dataloggers (BluLink and BluLogger), and wirelessly networked (BluGateway) for transmission to cloud based servers. The signals themselves are robust and can be transmitted over 500m of lead-wire. If broken the lead-wire can be twisted and taped together.
MULTIPLE ROD EXTENSOMETER – MPBX
YieldPoint recognizes that in many mining situation fast deployment of an ungrouted borehole extensometer is advantageous. The d-MPBX is a unique 1 to 6-Point Multiple Point Borehole eXtensometer (MPBX) based on a single rod design. The anchors are fitted with stainless steel extension springs that secure the instrument in a 38-50mm borehole. The d-MPBX incorporates digital signal processing to result in dramatically improved accuracy compared to similar priced existing technology.

The Geosense® GEO-XB2 borehole rod type extensometer range is used to measure and locate settlement, displacement and deformation in soil and rock.
It consists of a reference head and one or more in-hole anchors each of which is placed at a known depth and connected to the reference head by either a rigid or flexible rod running inside a flexible sleeve, which keeps the rod de-bonded from the grout.

Rated 0 out of 5
Drive-in piezometers, also referred to as push-in piezometers, are designed for installing in soft clays, organic or fine grained cohesionless soils typically with a SPT-N value less than 10. They are available with a CPT fitting or 1” BSP thread.
Depending on the depth and type of soil, they can either be pushed directly into the soil from ground level to the required depth or pushed into the base of a CPT test or drilled borehole.
