211 Temperature Monitor

The Lake Shore single channel 211 model temperature monitor is a high-precision, high-resolution, compact desktop temperature monitor with interface functionality, easy to use and integrate. When used in conjunction with appropriate sensors, 211 can measure temperatures ranging from 1.4 K to 800 K, and can measure temperatures under high vacuum and magnetic conditions. The standard configuration of 211 includes an alarm, relay, analog voltage or current output port (user configurable), and a serial port.

211 Temperature Monitor Product Introduction

The Lake Shore single channel 211 model temperature monitor is a high-precision, high-resolution, compact desktop temperature monitor with interface functionality, easy to use and integrate. When used in conjunction with appropriate sensors, 211 can measure temperatures ranging from 1.4 K to 800 K, and can measure temperatures under high vacuum and magnetic conditions. The standard configuration of 211 includes an alarm, relay, analog voltage or current output port (user configurable), and a serial port. For liquefied gas storage and temperature monitoring, low-temperature pump control, low-temperature refrigeration machines, materials science applications, and applications that require higher precision than thermocouples, 211 is a good choice.

Main features of 211 temperature monitor

Using appropriate sensors, the operating temperature can reach a minimum of 1.2K

Single channel sensor input

• Supports diode and resistance temperature sensors

0 V to 10 V or 4 mA to 20 mA standard industrial output

• Large screen 5-digit LED display

RS-232C serial port, alarm and relay

Sensor input reading capability

The Lake Shore 211 temperature monitor in the United States supports both diode temperature sensors and resistive temperature sensors. The type of input sensor can be set through the front panel of 211. To ensure measurement accuracy and 5-digit display resolution, 211 uses a 4-wire method and a 24 bit analog-to-digital converter for temperature measurement.

The Lake Shore 211 in the United States converts voltage or resistance into temperature based on the temperature response curve of the sensor. The standard temperature curves for silicon diodes and platinum resistance temperature sensors are included in the firmware of 211. There is also a non-volatile memory in 211 that can be used to store a 200 point user curve, which can be written to 211 through a serial port.

Lake S in the United StatesThe hore 211 temperature monitor comes with an RS-232C serial port and other interface features. As an independent monitor, it can be easily integrated into other systems, which is very valuable. Each function of 211 can be set through its serial port or front panel. The temperature data can be read up to 7 times per second through the serial port, and the front panel displays 2 updates per second. The high and low alarm functions can be used for error detection in lock mode; It can also be used in conjunction with a relay in non locking mode to perform simple on-off control functions. The analog output can be configured as 0-10V or 4-20mA.
