Overview

General Description

The Multipoint Sensor (MPS) provides a method to obtain moisture content readings over a large contiguous area using a single input. The MPS allows a single input to be used to obtain moisture content information over a twenty five foot span as compared to using several Point Moisture Measurement (PMM) sensors to cover a similar area.

The MPS performs a direct contact measurement of moisture content in materials susceptible to moisture absorption such as wood, gypsum, concrete or masonry.

The MPS returns a moisture content value representing the total parallel moisture content of all probed locations. Due to the nature of moisture content readings, wet readings overshadow milder conditions allowing the operator to differentiate between dry and wet conditions.

Sensor data from the MPS is transmitted to the Building Intelligence Gateway where temperature compensation and wood species correction factors are applied.

Features

Standard model covers 8 contact point locations over a 25 foot span
Built in temperature sensor allows for temperature compensation
Terminated on standard audio jacks for easy compatibility with SMT WiDAQs
Compact, low profile, very flexible design allows for easy deployment
Temperature data is transmitted and recorded along with Moisture Content Data
Sensor can be reused on various restoration sites

Applications

Applications of Product

MPS Sensor installed along base plate on basement floor.

Stainless Steel ¾” screws are driven into the MPS at pre-defined locations.

Any number of probes sets (screw pairs) may be deployed depending on the desired area to monitor and the MPS length.

For the 8 contact point model any number between 1 and 8 contact points may be used.
