SPS300A/B Series – Digital Pressure Detectors Intelligent Pressure Sensor and Switch

SPS300A/B Series – Digital Pressure Detectors Intelligent Pressure Sensor and Switch

Azbil SPS300A/B 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 a high reliability of more than one million pressure-cycle mechanical life. Liquid-filled dual diaphragms (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. SPS300A is a pressure sensor with current output and relay contacts. SPS300B is a pressure switch which 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 SPS300A must be mounted vertically. Different mounting orientation might cause measurement errors.

*If rain-proofing is required, seal the conduit hole with a water proof conduit and tighten the front cover firmly after wiring.
