Mass Flow Meters & Controllers
Vacuum Measurement and Control

The THCD-401 is a microprocessor-based four channel power supply and controller that can operate mass flow meters, mass flow controllers, and pressure transducers as well as vacuum gauges. It also provides stable output voltage levels to power these devices.
The instrument accurately measures and displays output from analog transducers. In addition, it can generate analog command signals to mass flow controllers. The bright, color LCD display is easy to view and understand; with a quick glance, the user can see each channel's status.

The THCD-401 provides stable ±15 VDC and +24 VDC levels which can be used to operate mass flowmeters, mass flow controllers, vacuum gauges including capacitance manometers, and linear pressure transducers.
Teledyne’s THCD-401 mass flow controller power supply allows ratio control of gases to create gas mixtures. In this video, we see how the THCD-401 operates while in ratio control. We also demonstrate how easy it is to set up the THCD-401.

Easy to Use

The THCD-401 Power Supply & Display features an intuitive front panel. A capacitance-touch ring control is used to quickly enter commands to mass flow controllers.
It's as easy as 1,2,3.

  1. Select the channel using one of the four buttons on the far left of the THCD-401.
  2. Use the left and right arrows at the bottom of the THCD-401 to move the blue cursor and select the digit to be adjusted.
  3. Dial the setpoint using the ring.

The buttons at the bottom of the front panel enable quick control of the corresponding flow controllers. For example, the user can quickly shut the valve of a mass flow controller by simply selecting the channel, and then pressing "Close". Immediately, bright blue "CLOSED" text appears on the screen to notify the user of the closed status.
The MENU button gives the user access to many setup features. However, setup is faster and easier via the instrument's internal webserver that can be accessed with the Ethernet port on the back panel.

Flexible Input/Output
THCD 401 - Rear Panel

The rear panel gives the user access to many convenient ways to interface to the THCD-401. In addition to the Ethernet port, there is also a USB port for serial communication. A programmable alarm output (mechanical changeover relay) can be used for process control. The "Interface" connector gives the user access to analog outputs from each of the individual channels.
