Overview

High-capacity high-performance sealed force sensor

The force sensors of the 3200 series offer a performance level equivalent to the 1200 series, with the added benefit of a fully hermetic stainless steel construction. The design of the 3200 series sensors is the result of 50 years of continuous improvement. The selection of strain gauges, construction, manufacturing expertise, and calibration enable a precision of ± 0.04% of full scale, exceptional repeatability (< 0.01%), and long-term stability (static accuracy: 0.04%). The construction is also nearly insensitive to eccentric loads (< 0.1% / cm) and transverse forces (< 0.25%), and highly robust, with an overload protection of 150%.

The operating temperature range is -55 to 90°C. Temperature compensation is applied between -10 and 45°C.

Installation

Bridge supply: 1-20 VDC

Installation 1: Tension only. The load is applied via a spherical rod end + nut. Sensor installation with base when the mounting surface has imperfections (see accessories). Screw types, tightening torques here
Installation 2: Compression only. The load is applied to the measurement surface. Sensor installation with base when the mounting surface has imperfections (see accessories). Screw types, tightening torques here
Installation 3: Tension/compression. The load is applied via a threaded rod + nut. Sensor installation directly on the surface. Screw types, tightening torques here
Installation 4: Compression only. The load is applied to the measurement surface. Sensor installation directly on the surface. Screw types, tightening torques here
Installation 5: Tension/compression, in-line, with base and rod ends on both sides of the sensor. Screw types, tightening torques here

Signal Conditioning and Acquisition

The output signal of the 3200 series sensors is unamplified. It is possible to obtain a complete measurement chain, wired and configured specifically for the application, by integrating a Display, an Analog signal conditioner/amplifier with voltage or current output, or a Data acquisition system for PC or PLC with included acquisition software.
