Sealed and high temperature precision switches contain a spring and set of contacts that convert mechanical energy applied to an actuator into an electrical output. Environmentally sealed switches are basic precision switches enclosed within a corrosion-resistant aluminum housing that seals the switch contacts from contamination. Hermetically sealed switches include those that maintain the contact in a gas-tight seal while transmitting force and motion to the switch mechanism through a metal diaphragm. High temperature versions have the switching element mounted on a ceramic base with a stainless steel enclosure. Wide variety of actuators, terminations, circuitry configurations, electrical ratings, contact materials and operating characteristics provide application flexibility. Meet military standards. U.S., European and other approval agency allow global use.
Best Used For:
Presence/absence detection where physical contact with an object is permissible as well as applications requiring compactness, light weight, accurate repeatability and long life such as are found in aerospace agriculture, transportation, construction, marine, ordnance and command and control equipment.

The LumaSense Photoacoustic Field Gas-Monitor Innova - 1412 is a highly accurate, reliable and stable quantitative gas monitor. Its measurement principle is based on the photoacoustic infra-red detection method. This means that the 1412 can measure almost any gas that absorbs infra-red light.
Appropriate optical filters (up to 5 + water vapor) are installed in the 1412's filter carousel so that it can selectively measure the concentration of up to 5 component gases and water vapor in any air sample. Further, the instrument can compensate for interference between the measured gases, using the unique Cross-compensation feature. The 1412's detection limit is gas-dependent but typically in the 10- ppm region.

PTC units for DIN bar application.
EH/FH heaters, installed separately from cooling unit, must be connected to TMC thermostat. When used to prevent cabinet condensate they should be eletrically connected also when cabinet is off.In this cabinet its better to install more heating elements with small heating power.In this way there is an optimal air temperature distribution.

Low surface temperature
Integrated thermostat
Quick mounting due to clip fixing
Double insulated (plastic)
Wide voltage range
Small size
Compact heater for the use in enclosures with electrical/electronical components. The design of the heater supports the natural convection which results in a high air-current of warm air.
The surface temperatures on the accessible side surfaces of the housing are kept down as a result of the heater design.
This model with plug-in thermostat does not require additional wiring.
The heaters are designed for permanent operation.
This heater is also available in a version without thermostat (CS 060).

✜ Real-time clock combined with timer function
✜ Editable programmer for up to 150 segments in five programs
✜ Nine pre-defined sets of parameters can be selected for the control
✜ Menu-driven operation in German, English, French or Spanish
✜ Function lights for heating, cooling and external control
✜ Error reports by means of bright LED lights, acoustic alarm and clear text message
✜ Vario pump with eight steps and adjustable limit of the pump pressure
✜ Integrated external control with cascade connection
✜ Supply temperature limit for the gentle heating of the external system

The LAUDA Integral T is the trademark which stands for extremely efficient process thermostats in a compact design. As generalist for fast, precise thermostating in the external circuit, they easily master the most demanding tasks. The most popular fields of applications are process engineering, production and research.
Integral T process thermostats make possible rapid thermostating with powerful heating and cooling capacities combined with a small active internal volume. This minimises thermal ballast and exothermic reactions are effectively controlled. Its compact construction is space-saving and makes the Integral T mobile.
Powerful for indirect thermostating tasks:
Integral T process thermostats are particularly suitable for the external thermostating of reactors, mini plants and calorimeters, whereby wide temperature ranges and fast temperature changes are essential. Fields of application: process engineering, production, research.
Performance profile of the Integral T:
✜ Programmer with max. 150 temperature/time segments, divided into 5 programs, with loop, change and pause function
✜ Parallel display of 2 temperature values with a resolution of 0.1 C
✜ Discharge pressure display
✜ External control via Pt 100 temperature probe or standard signal
✜ User calibration and LAUDA 2-point calibration
✜ Analogue inputs (3) and outputs (2), e.g. for control system. Can be configured to 0...10 V or 0/4...20 mA
✜ Malfunction indication for low level, overtemperature, pumps and cooling compressor
✜ Remote "malfunction” display via neutral contact
✜ Stand-by switch via neutral contact
