OnlineAngle – 360° inclinometer
DIGITAL 0 – 360° INCLINOMETER WITH MILLIAMP OUTPUT
The OnlineAngle sensor is designed for industrial-grade angle measurement under demanding conditions. It measures the full 0 – 360° range and provides a passive 4 – 20mA output.
Resolution: 0.1° over the full range.
The measurement is adaptively filtered based on angular speed — slow changes use slower filtering, and fast movements use faster filtering this ensures a responsive and stable reading in all conditions.
The sensor includes a terminal block for custom cabling, or is available with an M12 connector.
Angle measurement is done with accurate digital inclinometer IC.
- The angle- and temperature-compensated digital inclinometer ensures reliable results even in challenging, vibration-prone environments.
- Thanks to its high resolution, the sensor can also be used for measuring smaller angle ranges.
- The passive milliamp output enables easy and reliable integration with all automation systems.
Features
- Measurement range: 0 – 360°
- Resolution: 0.1°
- Input voltage: 24DVC
- Max load: 300 Ω
- Digital inclinometer
- Passive 4 – 20mA current loop
Included
- OnlineAngle with cable
- entry or M12 connector
- User manual
- (Cable ordered separately)
VC1 – Valve actuator
Versatile test device for the most common proportional valves.
The VC1 is a handheld testing device designed for proportional valve control.
Supported signals:
- 4(0) … 20mA input/output signals
- -10 (0) … +10V input/output signals
- Return signal scaling is selectable and adjustable (e.g., 4 – 20 mA output with 0 – 1.6 V feedback)
- Up to 2400 mA direct coil drive, for valves without internal electronics or when testing without amplifier cards
The VC1 can be powered via a 24 VDC supply, either from the included 24 V / 2.5 A adapter or directly from the valve’s 6+1 connector. Voltage and current values are displayed on the screen, allowing you to check power supply issues directly from the device. The device settings allow you to select flow, pressure or percentage as the scaling value for the electrical signal. Flow and pressure can be scaled freely according to the signals.
- Menu navigation is handled via a potentiometer and “Enable” switch, with clear status indicators.
- The machined aluminum housing ensures durability in industrial environments.
- The AMOLED display provides excellent visibility in all lighting conditions.
Features
- Compatible with most proportional valves on the market
- “Enable” voltage control on connector pin C
- Optional dead-man switch
- Adjustable current limit
Included
- Carrying/storage case
- Display unit
- Valve cable with 6+1 connector
- 24VDC power supply
- DIN‑A connector for valves without electronics
- System power cable
- User manual (QR-coded)
