Choose spot or rope probes for KS52; select KS61 by measurements and power configuration. [![KS52 Temperature, humidity & leak sensor](https://www.manthink.cn/assets/ks52.png) **KS52** Temperature, humidity & leak sensor](https://www.manthink.cn/en/products/sensors/ks52/) [![KS61 86-box indoor environment monitor](https://www.manthink.cn/assets/ks61.png) **KS61** 86-box indoor environment monitor](https://www.manthink.cn/en/products/sensors/ks61/) 02 ### Keep your existing meters Keep working water meters, electricity meters and instruments; acquire and parse their outputs with EdgeBus. Use the matching RS-485 or M-Bus collector and confirm protocols and programs before integration.

KS32 accepts dry contacts. KS31’s 4–20 mA and 0–10 V versions are separate configurations and must not be mixed. [![KS32 Six-channel dry-contact collector](https://www.manthink.cn/assets/ks32.png) **KS32** Six-channel dry-contact collector](https://www.manthink.cn/en/products/sensors/ks32/) [![KS31 Four-channel analog collector](https://www.manthink.cn/assets/ks31.png) **KS31** Four-channel analog collector](https://www.manthink.cn/en/products/sensors/ks31/) RECONNECT / KEEP EXISTING EQUIPMENT WORKING ## Start with the actual interface. Build on existing integrations. Confirm interfaces, power and device protocols before choosing collectors and adapters. EdgeBus integration documentation is available for these third-party devices.
