AV Sensors is pleased to introduce the MCT‑SM58A and MCT‑SM58D Series board‑mounted pressure sensors, designed for applications where precision, reliability, and fast response are critical. Built on our proven Multi‑Chip Technology (MCT) platform, these compact sensors deliver either high‑level analog voltage (SM58A) or high‑resolution digital (I²C/SPI) outputs, making them ideal for medical devices, laboratory systems, and environmental monitoring solutions.
Importantly, the MCT‑SM58A and MCT‑SM58D are direct replacements for the legacy SM5812 and SM5852 Series sensors, offering improved performance, enhanced diagnostics, and seamless drop‑in compatibility for existing designs.
Key Features at a Glance
Analog or Digital Output Options – Choose from high‑level analog voltage (0.5–4.5 Vdc) or 14‑bit digital pressure data with 11‑bit temperature readings via I²C or SPI.
Direct Replacements for SM5812 & SM5852 – Designed as improved, drop‑in alternatives for easy system upgrades.
High Accuracy – ±1.0% Total Error Band (TEB) across the calibrated range (−10 °C to +85 °C).
Fast Response – Analog update rate of ~2 kHz and digital conversion time of ~1 ms for real‑time feedback.
Built‑In Diagnostics – ASIC‑driven fault detection on sensor input and output lines for enhanced device safety.
Compact 0.600″ DIP Package – Top‑ported, board‑mount design for simple integration into OEM assemblies.
Rugged & Versatile – Operates from −40 °C to +125 °C with up to 5× overpressure capability.
Optimized for Medical Technology Applications
The MCT‑SM58A and SM58D are designed to meet the demands of advanced instrumentation where dependable pressure measurement is vital, including:
Medical Instrumentation – Supporting diagnostic devices, respiratory systems, and portable analyzers.
Blocked Filter Detection – Monitoring filtration systems in medical and industrial equipment.
Room & Ambient Pressure Control – Ensuring safety and precision in controlled environments such as clean rooms and patient care areas.
Why Choose the MCT‑SM58 Series?
At AV Sensors, we understand the unique requirements of medical and life‑science manufacturers. The MCT‑SM58A and SM58D Series provide:
Simplified Integration – Direct analog output or digital communication options for flexible system design.
Enhanced Safety – Onboard diagnostics for reliable, fault‑tolerant performance.
Proven Reliability – Built on robust Multi‑Chip Technology for long‑term accuracy and stability.
Seamless Upgrades – Directly replace SM5812 and SM5852 sensors with improved features and no redesign required.
Whether you need the straightforward analog interface of the SM58A or the precision digital output of the SM58D, these sensors deliver consistent, high‑quality performance for next‑generation medical and laboratory equipment.
