Compact pressure transmitters

The 21Y and 21C are thermally compensated to provide high Total Error Band accuracy over a wide compensated temperature range. They are rated for pressure ranges from 0-30 up to 0-10,000 psi, and available outputs include analog 4-20 mA (2-wire) and 0-10 Vdc (3-wire), ratiometric 0.5-4.5 Vdc and digital I2C. They are resistant to electromagnetic fields.

They feature a modular design that, when combined with proven piezoresistive silicon pressure measurement technology and state of the art conditioning electronics,  allows for a variety of pressure and electrical connections for maximum versatility for integration into new and existing hydraulic systems.
