Specs at a glance
| Parameter | Value |
|---|---|
| Level output | Reed switch (NO/NC selectable) – single or dual point |
| Temperature output | PT100 / K-type thermocouple / Temperature switch (NO/NC) |
| Level switch points | 1 or 2 (customer specified) |
| Max pressure | 20bar (brass) / 60bar (stainless) |

Single level switch vs Level + Temperature
| Feature | HNL10-A (Level only) | HNL10-B (Level + Temperature) |
|---|---|---|
| Function | Level switch only | Level switch + Temperature sensor – two measurements in one unit |
| Tank openings needed | 1 | 1 (same as single level switch – saves space) |
| Level output | Reed switch (NO/NC) | Reed switch (NO/NC) – single or dual point |
| Temperature output | Not available | PT100 / K-type thermocouple / Temperature switch (NO/NC) |
| Max temperature | 80°C | 105°C |
| Max pressure | Standard | 20bar (brass) / 60bar (stainless) |
| Mounting | Thread (G1/2, R1/2) | Thread (G1) or Flange |
| Material options | 304 / 316 / PP / PVDF / PTFE | Brass or 304 stainless steel |
| Best for | Simple level control in standard tanks | Tanks where both level and temperature need monitoring |
Need level only? HNL10-A does the job.
Need level + temperature from one installation point? HNL10-B is the choice.
When will use it?
Hydrothermal tanks - Level control + temperature monitoring in one opening. Brass or stainless body for pressure up to 60bar.
Chemical reactors - Small batch reactors where both level and temperature must be controlled. PT100 output for precise temperature reading.
Oil tanks / hydraulic reservoirs - Level alarm + oil temperature monitoring. Temperature switch output triggers cooling fan or heater.
Boiler feed water tanks - Level control + feed water temperature monitoring. K-type thermocouple option for higher temperature range.
Heat transfer oil systems - Level + temperature in thermal oil tanks. Dual switch points available for high/low level alarm + temperature protection.
Installation
Material & Pressure
| Rule | Why |
|---|---|
| Brass = 20bar max | Standard industrial pressure |
| Stainless 304 = 60bar max | Higher pressure applications |
| Max media temp = 105°C | Do not exceed – sensor accuracy drifts above this |
| No plastic options on this model | Brass or stainless only – HNL10-B is built for higher pressure/temperature |
