Transmitters of the LD series manufactured by KELLER are the smallest isolated pressure transmitters in the world. In addition to the standard versions of these sensors, KELLER recently started producing the LD Ei model, which is an explosion-proof version of these devices. Thanks to this, the range of applications for the transmitters has become even wider – they can now be used in explosive environments.
Due to their miniature size, LD transmitters are ideal for integration into devices and are the perfect choice for equipment manufacturers. Unlike pressure sensors, transmitters have a compensated digital I2C output and therefore do not require additional procedures such as signal amplification and temperature compensation. 
Thanks to the availability of an explosion-proof version, LD transmitters can now also be used as sensitive elements in equipment intended for use in explosive environments.
Transmitters LD Ei have a Customs Union certificate of conformity with the technical regulation "On the safety of equipment for operation in explosive environments".
