Wavelength Electronics Temperature Controllers

Wavelength Electronics Temperature Controllers

A temperature controller is used to maintain a device at a constant temperature. Two types of actuators are commonly used to precisely control the temperature of optics, lasers, biological samples, or other temperature-sensitive devices. One is a thermoelectric, or Peltier device. The other is a resistive heater. A precision temperature controller uses a current or voltage source to drive power through these actuators based on feedback from a temperature sensor. The temperature sensors are typically thermistors, RTDs, or linear devices such as the LM335 or AD590. With these types of sensors, stabilities of 0.01°C to 0.001°C are commonly achievable. Less precise sensors – thermocouples – can also be used for stabilities of about 1°C. The design of the system dictates the stability. If the sensor, actuator, and device being stabilized are poorly connected, the best controller in the world can’t help. The following block diagram shows a very basic temperature control circuit. Each symbol is defined in the table below. Each section is described in detail below. Temperature Controllers vary widely in feature set and performance. 

Expect very stable PI control with any of our temperature controllers – especially if you team them up with thermistor temperature sensors (< 0.001°C). These controllers can provide precision output to thermoelectric coolers or resistive heaters. The models that include a laser diode driver are indicated under the LD & TC header. Wavelength Opto-Electronic is the partner of Wavelength Electronics brand of quantum cascade laser drivers in Singapore, Malaysia, and Vietnam.
