Abstract

Remote indicating apparatus comprises a radio transmitter with its power supply and modulating system in the form of a block which can be encapsulated in resin so that it is safe in harsh and explosive industrial environments. The unit may be powered by thermo-electric and photo-electric assemblies or an electro-magnetic field and the transmitter may be modulated by measurement actuated devices and switches. <IMAGE>
