Model N-10 / N-11 Hazardous Area Non-Incendive Transmitter

Brand: WIKA Instruments

Type N-10 pressure transmitters are specifically designed to meet the durability and performance requirements of gas compressor systems. These pressure transmitters feature an industry standard 4-20 mA 2 wire signal output, NEMA 4X (IP 67) weather protection and are extremely resistant to pressure spikes, vibration and moisture intrusion. NACE MR-01-75 compliance provides extra resistance against sulfide stress cracking when exposed to gases containing sulphur.

Type N-11 pressure transmitters feature a flat, non-clogging diaphragm. This is designed for use with viscous fluids or media containing particulates that could clog the pressure port of the standard NPT version.

The transmitters are engineered to meet Class I Division 2 non-incendive protection requirements as well as, Class II Division 1 dust-ignition protection requirements in hazardous environments. Each undergoes extensive quality control testing and calibration to achieve a linearity of < 0.25% full scale.

In addition, each pressure transmitter is temperature compensated to assure accuracy and long term stability when exposed to severe ambient temperature variations.
