Features & Benefits of Moniteur’s Watchman VPT
Mechanical SPDT and DPDT Switches
The most popular switch for general purpose applications is rated 15A at 120 VAC and 2.5V at 24 VDC. Our standard mechanical switches are specified with higher operating forces and offer better resistance to freeze up. Gold Plated SPDT switches rated at 1A at 24 VDC are a low-cost alternative for intrinsically safe applications. DPDT Mechanical Switches rated at 10A / 125 VAC and 7A / 24VDC are also available. Specifications
NAMUR, PNP or NPN Inductive Sensors
A wide variety of industry standard sensors is available to interface with control systems found in today’s modern process plants. Specifications

Non-Contact TTL SPDT (proximity-type) Switches
These hermetically sealed switches set the standard for reliability. Tungsten TTL switches are used for high current AC and DC applications with a rating of 3A at 120 VAC and 2A at 24 VDC (100 Watts Max). Choose Rhodium TTL for low voltage / low current DC and Intrinsically Safe applications. Optional LEDs are also available on the Krystal TTL with Rhodium contacts. NOTE: Switches with Tungsten contacts are not recommended for DC signals lower than 50mA. Specifications
Optional 4-20ma Transmitters and 0-1K ohm Potentiometers
Current or Resistive Output are available for 0-100% / 4-20mA feedback. Our electronics have been designed for severe applications and have been proven to outperform our competition in the toughest of environments. Specifications

Features & Benefits of Moniteur’s Watchman VPT
Clear Ektar cover
offers excellent chemical resistance and strength
Indicator shaft is secured to the housing with
Moniteur’s engineered Loc-Ring Cam and Shaft Retention System, ensuring sensing accuracy and a multi-million cycle life.
“Flat cover” version available
without indicator is a cost effective option where visual indication is not required.
Environmentally sealed indicator
on the top of the unit prevents fogging or entry of contaminants. The indicator has a rated minimum life of 1,000,000 cycles.
Moniteur has indicators still in service with over 9 million cycles behind them!
Internal Switches and terminal block
are labeled for easier installation.
Optional thermoplastic quick-mount bracket
for NAMUR actuators stands up to corrosive environments.
Indicator is 100% adjustable
to any valve or actuator.
The industry’s only “true” visual valve position indicator
available for multi-port valves, adjustable to match the physical flow pattern of the valve. See the configurations below.
Available with Moniteur’s wide variety of switches and sensors
for today’s advanced control systems.
