Type 2000 - T2000 Intrinsically Safe
The Marsh Bellofram Type 2000 is a robust electronic instrument that regulates an incoming supply pressure down to a precise output pressure which is directly proportional to an electrical control signal. The secret to the Type 2000’s precise, reliable performance under a variety of demanding environmental conditions is a patented piezoceramic actuator with many industry-wide firsts.
Features:- ±0.1% of full-scale output typical (0.25% guaranteed); includes effects of hysteresis, dead band, and repeatability
