Python library for Thorlabs MTD415 OEM temperature controller

Simple wrapper for the Thorlabs MTD415T OEM temperature controller module.

Requirements

This module requires Python >= 3.5. It may also still work with Python 2.7 but is not explicitely tested for that environment.

• pyserial >= 3.4

Install

Install with pip

$ pip install git+https://github.com/nelsond/thorlabs-mtd415t.git

Example usage

from thorlabs_mtd415t import MTD415TDevice
from time import sleep

# create a new temperature controller instance with auto save enabled
temp_controller = MTD415TDevice('/dev/ttyUSB0', auto_save=True)

# set tec current limit
temp_controller.tec_current_limit = 0.5

# set pid gains
temp_controller.p_gain = 1
temp_controller.i_gain = 0.1
temp_controller.d_gain = 0

# clear any errors
temp_controller.clear_errors()

# set temperature setpoint
temp_controller.temp_setpoint = 15.025

# check current temperature after 10s
sleep(10)
temp_controler.temp # => 15.020

# close serial port
temp_controller.close()
temp_controller.is_open # => False
