Add to Cart
One end of the GCNA08 series pen type measuring head is connected
to the iron core of a frictionless LVDT, generating a voltage
output that is directly proportional to the position of the
measuring axis. The use of LVDT for measuring axis displacement
induction eliminates errors caused by friction or mechanical
hysteresis in the sensor. The LVDT output signal can be connected
to any standard signal processor and then transmitted to a metering
display, digital reader, or computer data acquisition system.
The other end of the measuring shaft has internal threads and can
accept tungsten carbon alloy probes to prevent wear and enhance
reliability.
In ordinary applications, the measuring axis is completely pushed
outward from the mechanical zero position of the measuring head by
a spring with a force of about 70 grams. The entire bearing,
measuring shaft, and LVDT are assembled inside an 8mm diameter
stainless steel tubular housing.
The tail end of the measuring head is a flexible tensile tight
polyurethane jacket cable that delivers the output of LVDT to the
signal processor.
Each measuring head is equipped with a replaceable tail piece that
can change the axial cable outlet to a radial cable outlet to
reduce the overall installation length in space limited
applications. The sealing of the measuring head meets the
requirements of IEC IP-65.
