Pressure Measurement & Control


Miniaure pressure transmitters from Instrotech

December 2011 Pressure Measurement & Control

Using the chip-in-oil technology developed by Keller, miniaturisation of OEM pressure transmitters is now made possible. Apart from an extremely compact design, the devices also offer impressive advantages in resistance to electrical noise fields of 250 V/m and high frequency resistance of up to 4 GHz.

The Series 4-9 LC with housings starting at a diameter of 11 mm, is an embedded system with the entire transmitter electronics in the transducer housing hermetically embedded in oil and all the key pressure measurement components protected against risk from humidity and condensation. These OEM transmitter capsules are ideal for integration in higher-order systems due to the selectable analogue and digital output signals. The CiO pressure transmitters are designed for 5 V applications and provide constant protection against overvoltage and polarity reversal on all lines up to 33 VDC.

With an analogue output, the series is characterised by fully integrated compensation and signal standardisation over the temperature range -40 to


150°C. The full scale pressure ranges extend from 1 to 1000 bar.
