Abstract
Two different ammonia sensors are introduced which are designed for the measurement of residual ammonia traces in a pipe of an ammonia cracker. The resistive sensor enables a continuous monitoring by an impedance measurement of the gas in a condensate, and allows the detection especially of low ammonia levels. The photoacoustic sensor operates in the gas phase directly.
