The BASI temperature transmitter series BTT784 is a compromising solution between the analog transmitters with fixed range and programmable transmitters. BTT784 transmitters allow on-site selecting input range and sensor type (for thermocouples) as well as transmitter reaction to sensor break by means of a group of soldering bridges (jumpers). The exact range can be adjusted by ‘zero’ and ‘span’ potentiometers. These transmitters have a special plastic cover to protect solder jumpers from the environment. Various mounting options are available: in sensor protection head type “B”, in a box with high protection class, or on a DIN rail. This series of transmitters is also applicable in Ex zones using external Zener barrier. Due to their flexibility, excellent resistance against electromagnetic disturbances, and low price, the BTT784 transmitters are easy-to-use and very widely applicable.
