RB21C4 Glass Microfused Pressure Transmitter FAQs

Straight answers to what buyers ask us most about Glass Microfused Pressure Transmitter.

The RB21C4 is a glass microfused pressure transmitter in the RB Xsense range from RB Automation for gauge pressure measurement from 0-10 up to 0-1000 bar. Its glass micro-fusion sensing process makes it fully integrated and leak-proof, and digital temperature compensation keeps readings stable. It resists corrosion, abrasion and vibration in demanding industrial environments.

The RB21C4 has ±0.5% FS accuracy at 25 °C, long-term stability of ≤±0.2% FS per year and a response time under 5 ms. Media temperature can be -40 to 125 °C with a compensated range of -20 to 70 °C. The housing is IP65 as standard, with IP67/68 available on customised builds, and the diaphragm and pressure port are 17-4PH stainless steel.

Glass microfused pressure transmitters like the RB21C4 are used in petroleum, hydraulic and pneumatic control systems, industrial process monitoring and control, machinery manufacturing, automated detection systems, pump stations and water treatment. They suit high-pressure points where leak-proof construction matters, with G 1/4, NPT 1/4, G 1/2 or NPT 1/2 process connections.
