Intelligent Pressure Sensor and Switch Model: SPS300A and Model: SPS300B

Intelligent Pressure Sensor and Switch Model: SPS300A and Model: SPS300B

Azbil Model SPS300A and Model SPS300B Intelligent Pressure Sensors and Switches are microprocessor-based high accuracy and high function digital pressure detectors. Accuracy is ± 0.25% FS with a high-speed response of 50 ms (63% response). The units have high reliability of more than one million pressure-cycle mechanical life. A Liquid-filled dual diaphragm (316L stainless steel) and a semiconductor-based pressure detection element are incorporated into the pressure detection unit. These detectors are used for gauge pressure measurements.

The Model SPS300A is a pressure sensor with current output and relay contacts. The Model SPS300B is a pressure switch that offers two-stage relay contact (independent) outputs. The structure is rainproof*—key operation and high visibility large digital indication. Smart functions ensure applicability to a wide range of sites: PV bias adjustable, adjustable indication figure, adjustable filter constant, keylock, adjustable hi-lo relay action, manual output setting possible, peak hold, and output scaling. The Model SPS300A must be mounted vertically. Different mounting orientations might cause measurement errors.

*If rainproofing is required, seal the conduit hole with a waterproof conduit and tighten the front cover firmly after wiring.
