The Hyoda KME-2 and KME-4 provide temperature switching through a remote sensing bulb and one microswitch contact.
The Hyoda KME-2 and KME-4 are fluid-filled temperature controllers with a remote sensing bulb and one microswitch contact. Their wall-mounted arrangement allows the switching instrument to be installed separately from the measurement point.
Choose KME-2 when local temperature indication is needed, or KME-4 when switching is required without a local indicator. Specify the temperature scale, sensing bulb, connection and capillary arrangement for the installation.

| Specification | Details |
|---|---|
| Measuring system | Liquid-filled or gas-filled, depending on configuration |
| Liquid-filled range coverage | −70 to 400°C |
| Gas-filled range coverage | −200 to 600°C |
| Published capillary lengths | Liquid-filled, single capillary: 10 m; gas-filled: 50 m |
| Published contact rating | AC 125 V or 250 V / 5 A |
| Contact terminals | At the lower part of the instrument enclosure |
Range coverage describes available configurations, not the scale of every instrument. Confirm the selected standard scale, switching point, bulb dimensions, connection and permissible capillary length before ordering.
A practical choice when an operator needs to read the temperature at the controller as well as use its switching contact.
Suitable when the application needs the switching function and a local temperature display is not required.

The Fluid-Filled Thermometer Range is an overview listing, not a single model with one specification. Compare the exact model, temperature scale, sensing bulb, connection and mounting before ordering. S6 and M6 both have 150 mm dials, but this does not establish interchangeability.
Contact Seacom with your temperature range, switching point, electrical load, connection and capillary length requirements. For a replacement, include photographs of the existing nameplate and installation so we can help check the appropriate model and configuration.
