Easily retrofit mechanical gauges such as Bourdon tube pressure gauges, dial thermometers, and pressure level gauges for digitalization!!
Simply attach a magnet to the central axis of the instrument’s pointer and replace the front glass plate with a unit that has a built-in plastic glass-integrated pointer reading sensor and a BLE wireless module.
Users can easily install it on existing equipment already in operation, enabling IoT/DX of mechanical instruments.
The product name, Salta® , is an abbreviation of the English words Sensor add – on lead to action , and conveys the meaning of “adding sensors to lead (conservation) activities.”

Kobata Retrofit IoT Sensor Unit “Salta®”
Made in Japan
Manufacturer: Kowata Keiki Seisakusho Co., Ltd.
Product name: Retrofit IoT Sensor Unit “Salta®”
Features
You can easily install this retrofit IoT/DX product on existing equipment, allowing you to start right away with the included software. This product is suitable for mechanical instruments such as Bourdon tube pressure gauges, bimetal thermometers, and other dial-type (round pointer type) gauges. Any type with a central axis pointer and replaceable gauge glass (removable front cover) is compatible.
To digitalize the instrument, simply attach a magnet to the pointer shaft and replace the glass with a resin glass integrated sensor unit. Users can easily install it themselves without any adjustment if they follow the position described in the instruction manual. For static pressure gauges (no pressure fluctuations), installation is possible even while the equipment is operating (when pressurized), eliminating the need to stop the machine.
No power supply or wiring work is required as the unit is powered by a lithium coin battery (CR2032) and uses wireless transmission via BLE. The low power consumption design ensures a battery life of approximately 1 year when transmitting every 15 seconds (theoretical value; actual battery life may vary depending on usage conditions).

By replacing the plate glass of an existing instrument with the retrofit IoT sensor unit “Salta®” integrated with resin glass (Note 1), you can transform the instrument into an IoT device. According to the Measurement Act, replacing the glass of a pressure gauge is considered a minor repair that users can perform.
To replace the lithium coin battery, simply remove the front cover cap of the Salta case and insert the battery vertically from the front. The case, made of ASA flame retardant material, offers high weather resistance. For outdoor use, select a vent-compatible product to prevent pressure changes inside the case due to temperature fluctuations. Depending on the application, the transparent resin glass can be made of either acrylic or PVC.

Use Cases
System configuration example
- Patrol inspection and remote monitoring can be used together. (The reception standby time during patrol inspection depends on the transmission interval.)
- Even if patrol frequency decreases, monitoring accuracy improves, and automatic meter reading eliminates reading errors, saving labor.
- Automatic meter reading from a distance reduces the risk of inspection work on instruments at high places or in dark places.
- Long-distance communication is possible by using a relay router that converts the BLE transmission data from “Salta®” to LPWA such as LoRa.
- Cloud connection is possible via public wireless internet lines from a gateway equipped with a SIM card.
- It is possible to import data into a PLC and link with on-premise systems.
