TC-10

npi's temperature measurement and control systems utilize small electronically compensated temperature sensors (thermistors, PT 100, c thermocouples). In addition, external temperature measuring instruments with analog outputs can be connected via BNC connectors. The standard calibration of the temperature inputs and outputs is 10 mV / °C (other calibrations are available). Control algorithms give precise temperature control to within typically 0.2 °C.

All systems (except MPS-20) can be operated in three modes: DIRECT: output voltage is set directly from the set-point digital control (0 - 100 %); no feedback. CONTROL: closed loop control using the internal temperature sensors. EXTERN: closed loop control using an external thermometer.

MTC-20/2S

Systems are designed for a large variety of applications:

TC 10 /20 series: Temperature controller (one or two channels, 19" cabinet) for "in vitro" recording chambers using resistive heaters (up to 12 V and 2.5 A / 2 A). These systems are equip­ped with two temperature sensors.

PTC 10 / 20 series: Peltier element tem­perature control units for heating and cooling purposes (one or two chan­nels, 19" cabinet) with bipolar high power outputs (up to ± 15 V and 5 A / 3 A). These systems are equip­ped with two temperature sensors.

MTC series: Small, low cost, single channel controllers (small desktop cabinet), for heating purposes. Featuring two temperature sensors and two displays for different measure points. Output power is 12 V / 1 A. MPS series: Small, low cost single channel DC power supply (desktop cabinet), designed for microscope stage applications. These systems have a high power, low-noise DC adjustable output (1.5 -12 V / 2.5 A) and can be used in conjunction with TC or MTC systems for powering heating devices like objective lens heaters o pre-heater perfusion systems directly.

All systems use digital displays that show the actual and desired temperature and the output voltage at the power output. In addition analog inputs and output (10 mV / °C or customized calibration make possible the connection to com puterized data acquisition and stimulate systems. Battery powered remote thermometers (PT 100 or thermocouple inputs) can also be added.

Each system is equipped with two electronic protection systems: Sensor input alarm: an electronic shut-off function disconnects the output if the sensor is disconnected, broken or short-circuited (indicated by a red ALARM lamp).
