A wide range of calibration transducers and their back-up electronics systems are readily available in the US. There are several types of calibration transducers that are suited for varied applications in engineering and technology.

Linear calibration transducers are strong, compressed SVLC sensors used in applications varying from metrology to heavy industry. These high-repeatability transducers can be based in any direction. Its salient features are - Ranges: 0-5mm to 0-50mm, linearity: greater than ±0.01% of range, low temperature coefficient and high tolerance to radiation and magnetic fields.

Another major type of measuring transducer is the angular type. It incorporates SVLC technology and present high accuracy and environmental acceptance. Flawless bearings guarantee repeatabilities that exceed 1 arc second. Its salient features are- Ranges: 20° and 60°, linearity: more than ±0.01% of range, and strong construction with minimal rotor inertia.

Non-contact measurement transducers have fixed parts and are typically suited for applications involving long life; environmental acceptance and very high repeatabilities are basic necessities. Its salient features include: 5 ranges from 0-1mm to 0-25mm, and high resolution with unique repeatability. It is very compact in design and usable up to 200°C at a stretch.

A Signal Conditioner is intended for application in ASL's variety of linear and angular transducers. Single- or dual-channel versions are available in two performance grades. Its important characteristics are: Linearity: ±0.01 or ±0.001% of full scale, high resolution / low noise, low temperature coefficient, and a 4-20mA current output option.

Another important calibration transducer is the Model D600, which is a flawless AC bridge noted for its very high exactness and permanence. The D600 is apt for single or multi-channel installations. Its important traits are: accuracy of ±0.004% full scale, resolution up to 1ppm Nul balance, and an AC transformer ratio bridge for exceptional long-term stability.
