Rdp lvdt amplifier
Applications calling for high frequency movements include switch testing, recoil testing, blast testing and high frequency component testing. It is important not to confuse sample rate with frequency response. The parameter being measured is the analogue frequency response, so that, for example, a mechanical oscillation of repetitions per second would be faithfully reproduced by the LVDT output. Where applications need to go faster, this can be enabled by modifications to the signal conditioning electronics. A spring return type is limited by the ratio of the mass of the amplifier compared to the strength of the spring which typically on a short transducer imposes a limit of the order of 10 Hz.

The key strength is no electrical contact across the transducer position sensing element meaning clean data, infinite resolution and long life. Available in a variety of mechanical configurations. Depending on your application and environment, we have both AC LVDTs with external signal conditioning and DC to DC units which have internal signal conditioning that are easy to use and set-up with voltage or 2-wire ma outputs. DC and AC powered versions and packages to fit all environments.
Analog amplifiers with panel meter and microprocessor based units with a very wide range of gain adjustment ensures that our amplifiers are compatible with the vast majority of LVDT and strain gauge sensors available from most manufacturers. The E amplifier unit also has a serial output and limit trips with optional relays.
With over 50 years of experience designing and manufacturing LVDTs and other types of linear position transducers we can offer a solution from our vast knowledge base to meet your application requirements. If a standard model is not suitable for your application, take advantage of our expertise and call us at to discuss your special needs with one of our application engineers and we will design a custom solution.

Measuring Position and Displacement With LVDT Sensors
Input Type: Strain Gauge, of Inputs: 1. Max Bandwidth: 5 kHz. The S7DC is an in-line d. It will operate from unregulated single or dual tracking power supplies and provide up to 10V output or mA with transducer signals from 10mV to 10V. This allows operation with some high output transducers DCT, etc.

Load Resistance Fig. Supply Voltage. Units may be master-slaved in systems where carrier frequency beating is a problem. The unit is housed in a robust aluminium case with connections via glands, all sealed to IP65 specification. All controls are internal with coarse range switches and fine adjustment potentiometers for gain and zero setting. Other controls include a zero-input switch, overrange indicator and pin-mounted components for frequency changing and half-bridge operation. Smith, C. The metal case should be grounded. This would usually be achieved by the use of fixing bolts through the case mounting holes into the grounded metal surface the S7AC is mounted on. NOTES: 1.

RDP LVDT Displacement Transducers
Written by Grant Maloy Smith , the data acquisition expert. In this article we will discuss how you can measure position and displacement with LVDT sensors , with enough detail so that you will:. They are used to measure linear displacement and position over relatively short distances. There are LVDTs on the market today that can measure movements as small as several millionths of a cm microinches or even up to about 0. An LVDT consists of a tube that contains a freely moving shaft aka armature. The base of the tube is mounted to a fixed position, and the end of the rod is affixed to an object whose position will be moving in a linear back and forth fashion.

Products include: standard and custom engineered LVDTs to fit your application as well as accessories and signal conditioners. The strength of the LVDT sensor's principle is that there is no electrical contact across the transducer position sensing element which means clean data, infinite resolution and a very long life. Stroke lengths are from 0.

It also incorporates a digital display. Our digital indicator unit is microprocessor based and has an auto-zero function to zero the transducer display on command. Where the transducers are identical, two may be connected to one digital indicator using the optional second LVDT amplifier input card. The digital indicator may then be set to display either of the input channels as well as sum and difference. Unlike many signal conditioning units of its type, the E has a high bandwidth analogue output of Hz.
