Temperature Measurement Probes with or without built-in Transmitter Temperature Probe Temperature Probe Temperature Probe with built-in transmitter with built-in transmitter without transmitter and thread fitting Probes shown 75% of natural size OxyGuard temperature measurement probes are available with precision thermistor temperature sensor or with 4-wire Pt100 sensor. The thermistor version is also available with built-in 4-20 mA 2-wire transmitter. The probes are designed for use between -5°C and +45°C. With housing of POM and sensor tip of stainless steel these probes are ideal for use as simple temperature sensors in water, air or gas in fish farms and similar uses. The thermistor version without built in transmitter is designed for use with OxyGuard monitoring units. The version with built-in transmitter is a true 2-wire 4 to 20 mA device. When connected to a source of voltage between 14 and 32 volts it regulates the current in the circuit between 4 mA and 20 mA according to the temperature.

Technical Information Technical Advantages OxyGuard temperature probes are robust, accurate and easy to use. They are filled with a special compound that protects against moisture. As standard the probes are fitted with 7 m cable, but they can be supplied with other lengths on request. The sensor in both types of probe consists of a stainless steel cylinder containing the thermistor or Pt100 element. This sensor tip is fitted to a black plastic housing. Standard types of housing are shown overleaf, but others can be supplied on request, e.g. to fit other pipe threads or fittings. Probe with...
