• The devices of the series Precont PS with integrated digital evaluation electronic are compact pressure switches for supervision, control and continuous measurement of pressures up to 1000 bar. By this the replacement of mechanical contact manometer is possible. Besides a bright luminous 4-digit LED display there are up to 2 free configurable PNP switching outputs incl. 4...20mA output available. The use is possible in gases, steams, liquids, oils and dusts inside closed containers or pipelines at process temperatures from - 40°C up to +125°C. The extremely short reaction time of 3ms allows also the use in hydraulic units and in pneumatic applications.

• The pressure switch Precont PS is mounted in the wall of the pressure container or of the pipe.

Characteristics of the metallic measuring membrane - Precont PSM:

• The system pressure is applied to the metallic membrane and causes there a deflection of the polysilicon resp. of the thin film strain gauge at the back side of the membrane. At measuring ranges of 0...10 bar and lower the pressure is transmitted to the polysilicon strain gauge by a pressure transmitting liquid.
• The metallic membrane offers excellent characteristics like high pressure and pressure blow strength up to five times the nominal pressure, front flush construction, good reproducibility and hysteresis and also good long term stability and a low temperature influence.

Signal processing:

• The pressure signal that is transmitted from the membrane to the strain gauge is transformed into an electrical signal that is recorded and processed in high resolution by a processor.
• The pnp switching output resp. outputs are driven according to the respective settings.
• When using the analogue signal current output the recorded pressure signal is adjusted according to the settings and transformed into a high resolution output signal of 4...20mA.
• By 3 sensor keys and the four digit LED display all settings for the pnp output resp. outputs, the display and also the analogue output can be set resp. adjusted.

The human body is comfortable only in an environment where the

temperature and the air movements are kept within established limits.

For the comfort and good health of human or animals, the black ball

thermometer gives a direct measurement of the average radiant

temperature.

This temperature, perceived by the body, is radiated by all surrounding

surfaces, walls, floor, furniture and equipment.

The black ball thermometer is particularly useful in working area’s

veterinary laboratories and animal breeding.

Developed and manufactured

by KIMO, the Black Ball

Thermometer is for measuring

radiant temperature.

Based on the black body

principle, it consists of one

sphere, which is equipped with

a liquid expansion

thermometer, Pt 100 or

thermocouple temperature

probe .

It’s an accurate, reliable and

user-friendly instrument.

It''s also adaptable on every

types of thermometers.

• For operations in Ambient Temperature 100*C or 125*C, for example extremely close to Ladle  or Hot Metail Applications in Steel Plants or In Chemical Cracker Plants in Oil and Petro Processing.
• A ,,shielded" or ,,flush' proximity switch will not be affected by surrounding metal.
• An ,,unshielded' or ,not flush" proximity switch must have an open space around the active face. d >d d Steel shielded shielded If proximity switches are installed opposing one another, the op posing switches must be installed with a spacing of 3 x the switch diameter between them.
• Installation side by side To avoid interference in side by side installations a minim um clearance distance between the switches must be observed.> 3 x d F F Steel unshielded F = free zone d > 3 x F F > 2d Steel unshielded F = free zone d a d a d > 3 Sn Measuring plate For shielded side by side installations the interspace is a > d ( interspace > diameter> ) If unshielded proximity switches are to be installed side by side the following spacing must be observed: a > 2 d (interspace > 2 x diameter) Cable Installation
• To avoid pick up of induced voltage and current peaks, connecting wires for proximity switches should be installed separately from motor-magnet or valve-wires Cable length
• Extremely long cables will add a capacitive bad to the output and increase interference. Cables for AC-and DC-switches should not exceed 100 m (300 ft) substantially. Cables for NAMUR-switches should not exceed 250 m. (750 ft)
• Magnetic fields Strong magnetic fields may increase the sensing range or even trigger off a proximity switch. Radio frequencies may also influence a proximity switch. At installations with strong sources of radio interference the proximity switch and cable should be shielded. Actuating area The actuating area is a limited zone in front of the active face of a proximity switch. Within this area a target will be detected and turned into a switching signal'. Sensing range 
• Nominal sensing range Sn The nominal sensing range Is the value obtained when (he ambient temperature is held at 20 ~C and voltage between 12-24 V. Under
• these conditions the switching point must be within a tolerance of 10 %.
• Real sensing range Sr This is the actual switching distance for an individual proximity switch lt is measured at nominal voltage and ambient temperature of 20 ºC and will be between 90 % and 110% of Sn.
