SMT-9700
High-Resolution Non-contact Displacement
Measuring System
User’s Manual
This apparatus, when installed and operated per the manufacturer’s recommendations, conforms with the
protection requirements of EC Council Directive 89/336/EEC on the approximation of the laws of the
member states relating to Electromagnetic Compatibility. Refer to the SMT-9700 Declaration of Conformity
or contact Kaman Precision Products for details.
Description
Kaman’s Model SMT-9700 is a non-contact, high-precision, analog position measuring system. The
system operates on proprietary Pulse Width Modulation Circuitry. It is a lead free, RoHS compliant,
CE Marked design. This system can be utilized for precision static and dynamic measurements of
conductive targets. It is primarily for OEM use or where high resolution is of primary importance, and
where the user can correct outputs with higher non-linearity.
The SMT-9700 system consists of two subassemblies: sensor with integral cable, and signal
conditioning electronics module. The sensors are connected to the electronics with push-pull
MCX style coaxial connectors. It is available in 1, 2, or 3 channel configurations.
The SMT-9700 is specifically configured for each unique application. Refer to the calibration
record supplied with each system for; sensor model, sensor cable length, target material, range,
offset, and output. Output is an analog voltage with a maximum span of 10 VDC. Typical outputs
are 0-10, ±5, ±2.5, etc. Connections to the SMT-9700 are shown below. Note the channel returns
(pins 1, 4, and 8) are common and are not connected to Ground (pins 3 and 7).
