📦 Product Overview: FS‑SMSB‑1534D
The FS‑SMSB‑1534D is a digital point‑level switch sensor from the FS series, designed for reliable detection of liquid or interface presence at a fixed point. The suffix “D” denotes its digital switch output nature (e.g. discrete digital logic output). It is built to perform in industrial environments where rapid, repeatable level detection is required.
This sensor is engineered to detect the presence or absence of fluid at a threshold level, triggering a digital signal (high/low) that can be used by control systems. With a compact, robust housing and chemically resistant materials, the FS‑SMSB‑1534D is suitable for applications ranging from chemical processing to water treatment, where space is limited but reliability is essential.
🧰 Applications
-
High or low level alarm detection in tanks
-
Pump protection (dry run prevention)
-
Overflow detection and shutoff control
-
Interface detection (e.g. oil/water separation)
-
Integration with PLC or relay logic for process control
-
Detection of fluid presence in process piping or small chambers
⭐ Key Advantages

❓ Frequently Asked Questions (10 Q&A)
Q1: What does the “D” suffix in FS‑SMSB‑1534D signify?
A1: The “D” indicates that this variant provides a digital switch output (binary, on/off) rather than an analog signal.
Q2: Can the sensor be used for continuous level measurement?
A2: No — FS‑SMSB‑1534D is a point-level switch sensor. It detects when a fluid (or interface) reaches a specific height, and outputs a digital signal.
Q3: What is the switching response speed?
A3: The response time is very fast, typically ≤ 10 milliseconds, enabling real-time detection for control systems.
Q4: Is the sensor resistant to corrosive fluids?
A4: Yes, its wetted parts are made from corrosion-resistant metals and industrial polymers, designed to endure many chemical environments.
Q5: How should this sensor be mounted?
A5: It can be mounted via threaded insertion, flange fittings, or insertion ports — ensuring the sensing tip aligns with the fluid level to be monitored.
Q6: What is the working temperature range?
A6: The sensor is rated for operation from –20 °C up to +80 °C, suitable for many industrial and environmental conditions.
Q7: Does it require calibration?
A7: It is factory calibrated for switch action; no user calibration is typically required. Periodic verification is recommended in critical systems.
Q8: What happens if the sensing tip gets fouled or coated?
A8: Deposits or coatings on the sensing tip may prevent correct detection or cause false triggers. Periodic cleaning is advised for reliability.
Q9: How is the digital signal integrated with control systems?
A9: The switch output can be wired to PLC digital inputs or relay circuits. Use proper pull-up or pull-down resistors as needed by your control logic.
Q10: What is the expected switching life of the sensor?
A10: The electrical lifetime exceeds one million switching cycles, ensuring long-term reliability in repetitive operation.
