KL-91 Series PFA/PTFE Pressure Transmitter

Brand: Malema

The KL-91 is a pressure transducer suitable for use in monitoring pressure of various high-purity fluids. 

The superior design provides for minimal “dead volume” which reduces the potential for contamination of the measured fluid. 

The KL-91 is available in two construction type: inline or insertion. 

The body construction meets IP-65 requirements and EMC resistant the level of CE.
