Surveyor SV4B Flammable gas measuring controller
Specially designed for very small boiler rooms, the Surveyor SV4B controller prevents the risk of explosion due to the presence of flammable gases in the ambient air. The small module is mounted on a standard DIN rail and can be easily integrated into any existing box or control cabinet, thus reducing installation costs.
Smaller size, easier installation and lower cost are the main advantages of this datalogger. Used only with Oldham's Wheatstone bridge series (OLC10 or OLC100), the Surveyor SV4B controller combines simplicity and reliability with an excellent price/performance ratio. Detailed description
The Surveyor SV4B gas detector is designed to be integrated with a simple click in an electrical cabinet near the control devices. It is a single-channel flammable gas detection unit to which one OLC10/OLC100 sensor or two OLC10 TWIN sensors can be connected. It has two potential-free alarm relays for the control and the acknowledgment of these, and can be manual or automatic.
The assets of the Surveyor SV4B
- Mounting on symmetrical DIN rail (omega rail) for integration in a box or in a control cabinet
- 1 input available for 1 OLC10/100 or 2 OLC10 TWIN sensors
- 2 alarm levels: alarm1, alarm2 + fault
- 2 potential-free alarm relays for the control systems
- Permanent self-control of the measuring circuit
- Excellent quality/price ratio
