IKA 68 High-precision pressure transmitter IKA 68 is conceived for recording- and monitoring of absoluteand overpressures of liquid, as well as gaseous media for measuring spans 4 bar up to 100 bar. By integration of a separate temperature sensor as well as the conjunction of the pressure- and temperature signals in the internal microprocessor a higher stability and accuracy over the full rated temperature is being reached. The robust full metal version and the resulting EMC-stability (double test level) predestines the IKA 68 for industrial apllications. The use of stainless steel grants a high IP-degree of protection and high chemical resistance. With its two switching outputs, which are absolutely freely programmable regarding switching function, switch point and switch hyteresis, as well as the integrated RS-485-port, the IKA 68 constitutes a synergy of pressure transmitter and pressure switch in only one instrument. Simple, pressure controlled switching operations can be realised without additional SPC or logic modules and can be administrated by the user at any time with the software via RS-485.
