The temperature package of the transformer oil surface temperature controller is inserted into the oil hole on the top of the transformer oil tank and changes with the temperature of the transformer oil. When the temperature reaches the set point, a micro switch is driven to output on/off control signals to drive the cooling system and achieve the purpose of controlling the temperature rise of the transformer. It can output Pt100 platinum resistance signals and 4-20mA current signals for use in digital meters and computer systems, achieving all-weather unmanned power station management.
Basic parameters:
| Output signal: |
Pt100 platinum resistance signal, 4-20mA current signal (AC/DC220V or DC24V power supply). |
| Working conditions: |
Environmental temperature (-40~+55) ºC, relative humidity ≤ 95%. |
| Measurement range: |
Default (0-150) ºC, optional (0-160) ºC, (-20-140) ºC, (-45-150) ºC, etc., see the minimum and maximum scales on the dial. |
| Accuracy: |
Level 1.5, allowable error: ± (measurement range x 1.5%). |
| Switching performance: |
Four or six sets of adjustable switches, each set of switches can be set freely within the full range. |
| Switch action error: |
± 2 ºC. |
| Poor switch switching: |
(5 ± 3) ºC. |
| Rated power of switch: |
AC220V/5A, DC110V/3A. |
| Temperature bulb size: |
Φ 14 x 150 mm, with an installation thread of (M27 x 2) mm. |
| Capillary length: |
Standard configuration of 6m (other tail lengths can be customized) |
| Protection level: |
IP55 |
| External dimensions: |
304 * 192 * 103mm |
| Installation dimensions: |
Two types, one types is 80mm x 100mm, 4- Φ 8; Another type is 144mm x 210mm, 3- Φ 7 |
