Step 1: Choose Screen Size and Aspect Ratio

Industrial monitors range from 7" to 55". Choose based on viewing distance and information density:

7", 10", machine-mounted, close viewing
12", 15", standard SCADA workstation
17", 21", control room, multi-parameter display
24", 32", supervisor overview screens and video wall tiles

Step 2: Brightness for Your Environment

250 a 350 nits, standard indoor, ambient-lit environment
500 a 700 nits, bright factory floor with overhead lighting
1000+ nits, semi-outdoor, near windows, direct sunlight exposure

Step 3: Touch Technology

Resistive touch, works with gloves; single-touch only; lower cost; suitable for simple HMI use
Capacitive touch, multi-touch, fast response; requires bare fingers or conductive gloves
PCAP (Projected Capacitive), most responsive; water-rejection algorithms; best choice for new installations

Step 4: IP Rating and Mounting

For panel-mount or open-frame monitors, confirm the front-panel IP rating. IP65 is the minimum for most factory environments. Open-frame monitors (no bezel or case) are installed inside custom enclosures and can have full IP65/IP67 front seals.

Step 5: Interface

Check that the display interface (HDMI, DisplayPort, VGA, DVI, or LVDS) matches your computer's outputs. For embedded systems, LVDS or eDP connections are common. For external monitors, HDMI or DisplayPort is standard.

TSL Automation supplies Avalue open-frame and panel-mount industrial monitors in sizes from 7" to 21.5", contact us to find the right display for your project.

Preguntas frecuentes

Screen size should match the amount of data displayed and the viewing distance: 4.3", 7" for single-machine, close-proximity operator controls; 7", 10" for multi-zone machine interfaces; 10", 15" for production line supervision and multi-PLC displays; 15", 21.5" for process overview screens viewed from 1 a 3 metres. Avoid oversizing, a larger screen requires more complex HMI design without necessarily improving usability.

Resistive touch uses pressure activation, it works with gloves, styli, and wet fingers, making it robust for harsh factory environments. PCAP (Projected Capacitive) uses electrical field sensing, it provides multi-touch, faster response, and a smoother surface, but standard PCAP does not work with heavy gloves. Choose resistive for environments where operators wear thick gloves; choose PCAP for cleaner environments where a more intuitive interface is preferred.

For indoor factory environments with standard lighting, 300 a 500 nits is sufficient. For outdoor or high-ambient-light environments (near windows, skylights, or outdoor installations), specify 700 a 1000 nits with anti-glare coating. Higher brightness comes at the cost of higher power consumption and heat generation, so don't over-specify unless the installation environment genuinely requires it.

Production floor displays should have IP65 front panel sealing minimum, dustproof and protected against water jets from any direction. For wash-down environments (food, beverage, pharmaceutical), IP66 or IP69K is required. The IP rating must apply to the installed configuration (front panel mounted into the enclosure), not just the display module in isolation.

Yes, TSL Automation Solutions supplies Avalue industrial monitors and open-frame displays, plus Cermate HMI panels with integrated displays, across all sizes from 4.3" to 21.5". We provide size, brightness, and touch technology recommendations for your specific installation. Contact our Mumbai team for pricing and availability.
