he 18-1000 Transducer is an electro-pneumatic device that reduces a supply pressure to a regulated output pressure that is directly proportional to an electrical input signal. It uses a wide supply pressure range between 125 and 700 kPa (18-100 psig), and is small in size with low air consumption. An integral pneumatic volume booster is included in the design to provide high flow capacity (up to 12 SCFM).

The Type 1001 is a patented family of electropneumatic instruments that reduce a supply pressure to a regulated output pressure which is directly proportional to a two-wire current or three-wire voltage input. This design incorporates closed loop sensing of the output pressure to achieve excellent accuracy and vibration stability. It also features a unique damping circuit which can be adjusted to prevent overshoot and actuator "hunting." Model selection includes General Purpose, NEMA 4X, Explosion-Proof and Instrinsically-Safe.

The DEVAR Model 18-268B is a two-wire pneumatic to current transmitter. It accepts a pressure input and provides a proportional 4 to 20 milliamp output. This transmitter features a piezoresistive silicon, pressure transducer, which provides excellent signal conversion and long term stability. The transducer includes laser-trimmed resistors, which provide temperature compensation over a range of 0 to 50 °C as well as interchangeability of ±1%. The pressure transducer is unaffected by vibration and does not consume signal air. All internal parts which come in contact with the input media are either silicon or gold plated kovar. The 18-268B provides easily accessible span and zero pots for calibration as well as a linearity pot which is used to calibrate out any nonlinearity which might be present in the pressure transducer. Other features of the 18-268B include effective RFI protection in the 20 to 500 MHz frequency range and a rugged die cast aluminum NEMA 4X enclosure.
