Product Headline
|
Highly robust gas specialist for fluctuating process conditions as remote version with up to 4 I/Os.
Flexible device with user-definable gas mixtures for demanding measuring tasks.
Accurate measurement of natural and process gas in the chemical as well as oil and gas industries.
|
|
Sensor Features
|
Maximum reliability even with humid or wet gas – sensor design insensitive to condensate. High-performance process control –
real-time pressure- and temperature-compensated values. Efficient solution – multivariable, no pressure loss.
Direct measurement: flow, pressure & temperature. Wetted parts: titanium / 316L. Maximum measuring accuracy: 0.5 %.
|
|
Transmitter Features
|
Full access to process and diagnostic information – numerous, freely combinable I/Os. Reduced complexity and variety – freely
configurable I/O functionality. Integrated verification – Heartbeat Technology.
Remote version with up to 4 I/Os. Backlit display with touch control and WLAN access. Standard cable between sensor and
transmitter.
