What are the specifications for transformer oil level sensors?

Transformer oil level sensors typically have specifications that include a measurement range of 0 to 100% oil level, accuracy within ±1%, and a response time of less than 1 second. They should operate within a temperature range of -20°C to 70°C and be compatible with various oil types. Additionally, sensors often feature a robust design for harsh environments, with IP65 or higher ingress protection, and may include output options like 4-20 mA or Modbus for integration with monitoring systems.
