摘要： Disclosed is a field device of automation technology comprising a measuring transducer for ascertaining a measurement signal and a measurement transmitter for output of the measurement signal ascertained. The field device has at least one housing of the measuring transducer and/or of the measurement transmitter, in which electronic components of the measuring transducer and/or of the measurement transmitter are arranged, characterized in that the electronic components are embedded in an epoxide polymer foam, which is a reaction product of a self foaming, potting compound comprising at least the following components: 25 to 75 wt-% of a diglycidyl ether resin; at least one amine containing hardening system comprising a Mannich base; and at least one foaming agent, and a method for manufacturing a field device of automation technology.
