QDY60B-W High-Temperature Level Transmitter for Hot Process Media

Technical Specifications

Zero Temperature Drift：≤±0.05% F.S./℃ (within full compensated temperature range)

Sensitivity Temperature Drift：≤±0.05% F.S./℃ (within full compensated temperature range)

Long-term Stability：≤0.25% F.S./year; no drift from continuous high-temperature immersion

Step Response Time：≤800ms (10% → 90% full scale, steady-state condition)

Thermal Damping：Software-adjustable multi-level filtering; suppresses reading jitter from liquid turbulence and pump surges

Safe Continuous Overpressure：200% F.S.; no permanent diaphragm deformation or zero shift

Burst Pressure Rating：≥300% F.S.; withstands sudden pressure spikes and water hammer

Zero Recovery Performance：≤0.15% F.S. offset after overpressure release

Heat Dissipation Design：Integrated finned heat sink on transmitter head; reduces heat conduction to internal electronics

On-site Calibration：Zero reset and span fine-tuning via head keypad; no need to drain the tank for routine adjustment

Local Display Function：Backlit LCD shows real-time level, percentage, engineering unit and fault code

Output Short-circuit Protection：Fully supported at transmitter head; no permanent component damage under continuous short circuit

Reverse Polarity Protection：Full power supply reverse tolerance; no internal circuit damage with reversed wiring
