Compact housing developed by i2O to use KELLER transmitter

KELLER had been delivering compact sensor headers to i2O since 2008 for use in its data loggers. In 2012 i2O started to develop a new range of data loggers and worked with KELLER to integrate the D-Line PA-20D data transmitters into the new products. A compact customised housing was developed by i2O, in conjunction with KELLER development that incorporates a quick release coupling and allows the transmitter to interface directly with the circuit board, allowing a modular build that aids assembly of the product.

By utilising the I2C bus interface of the transmitter, pressure readings can be read directly into the logger from the transmitter. This means that no analogue circuitry is necessary within the loggers. To achieve the high accuracy requirements of i2O over a temperature range requires specialised calibration by KELLER that is programmed directly into the transmitter during manufacture. This enabled i2O to bring to market an accurate, reliable and affordable logger which delivers timely and valuable data that its clients can rely on for decision making.

The success of this project is not only based on technical advantages, it is also characterised by the very close working relationship between two highly competent companies and the customer's direct contact with the developing department, manufacturer and representative.
