Single-axis inclinometer HCA516T

RS-485RS-422TTL

Product Overview
HCA516T is a high-precision single-axis digital inclinometer designed for industrial tilt measurement with selectable ranges and multiple output interfaces.

• Single-axis inclinometer (X or XY option)
• Measure range: ±1° up to ±90° (selectable)
• Wide supply voltage: 9–36 V
• Operating temperature: -40 to +85 °C
• Resolution: 0.001°
• High anti-vibration and shock resistance
• Protection class: IP67

Product Description
HCA516T integrates a high-precision 16-bit differential A/D converter and multiple filtering algorithms to deliver stable, repeatable tilt measurements. The device provides optional interface outputs (RS485 / RS232 / RS422 / TTL / CAN / MODBUS) and supports temperature-based drift compensation via a built-in digital temperature sensor. Output frequency response is configurable up to 100 Hz (standard options to 50 Hz). The robust industrial design and wide temperature tolerance make the unit suitable for harsh control environments and long-term deployment.

Scope of application
