This industrial wall-mounted transmitter matches built-in or remote probes, covering wide temp and full RH measuring ranges. It supports 4-20mA/voltage analog outputs plus RS485 Modbus, with dual relay alarms, IP65 casing and large LCD for real-time environmental monitoring in warehouses, workshops and HVAC systems.
IP65 sealed protective housing: IP65 waterproof casing blocks dust, moisture and splashes, avoiding circuit corrosion. Less frequent disassembly cleaning and replacement cuts regular maintenance workload.
Stable sensing chip with low drift: High-precision sensor features tiny temperature & humidity drift, requiring infrequent calibration. It eliminates repeated on-site correction labor and calibration reagent costs.
Anti-pollution probe structure: Probe resists interference from volatile organics, slowing sensor contamination. It extends service intervals and reduces frequent probe cleaning or replacement expenses.
Robust EMC anti-interference performance: Built-in ESD and surge protection shields signal from field electromagnetic noise. No frequent troubleshooting of jumping readings saves inspection man-hours.
Long service life with wide working range: Adaptable to -40~120℃ harsh environments without easy aging. Fewer equipment failures lower after-sales repair and spare part replacement costs.
Unified digital Modbus communication: Centralized data reading cuts on-site patrol frequency. Staff do not need separate inspection for each transmitter to lower daily maintenance labor input.
Quick sensing response: 8-second T63 rapid response captures real-time temp & RH shifts instantly, avoiding delayed data that fails to reflect sudden environmental fluctuations.
24/7 uninterrupted operation: Stable 11–26VDC power support realizes round-the-clock continuous monitoring without manual restarts or frequent device checks.
Real-time dual digital display: Large LCD simultaneously shows temperature and humidity values, offering instant on-site visual climate data without delayed signal reading.
Timely signal output linkage: 4-20mA analog and RS485 Modbus transmit fresh data to PLCs instantly for automatic climate adjustment without lag.
Quick abnormal alarm trigger: Dual relays rapidly activate alerts once thresholds are crossed, securing prompt intervention against out-of-standard climate conditions.
