		Avanti Digital Quartz Transducer Simulator.

Quartz Transducers are widely used in the oil industry for measuring downhole pressure and temperature with very high accuracy. The latest generation of Quartzdyne Transducers (Quartzdyne DM, DS and DX series) include high resolution frequency counters and provide a two-wire serial I2C interface instead of the traditional frequency outputs. Due to their digital interface they are called digital pressure transducers. The Avanti Digital Quartz Transducer Simulator substitutes such a digital Quartzdyne pressure transducer and facilitates testing of data acquisition systems in the absence of a real transducer. Pressure and temperature values can be set independently by means of two rotary switches. Constant values or ramps can be selected, which produce regular saw-tooth edges every 10 minutes. This is particularly useful for testing the time-keeping of a logging system. Two jumper links are provided for setting the device address allowing up to 4 devices on the same I2C bus. Activity on the I2C bus is indicated by an LED, which flashes up whenever the simulator is being polled successfully for pressure or temperature readings. The Avanti Digital Quartzdyne Simulator can also be configured to simulate typical failure modes of earlier digital Quartzdyne transducers (see the user manual for details). This feature may be used to verify, that the logging system is able to recover in such cases. Model-No: AVA-02 Price: £145.- + VAT. Please contact Avanti for price in USD or EUR.
