Matsuo Thermostat Products other than thermostats


	Moisture controller

		Application: Garbage Processing Equipment / Rainfall Sensor / Icing Sensor The Matsuo moisture controller utilizes a thermo sensor containing a thermistor or diode and a compact heater in its closed housing. The Matsuo moisture controller is classified as a temperature capacity method and applies radiation with moisture. The biggest advantage of the Matsuo moisture controller is its closed housing sensor. There is a typical application for controlling the moisture of Garbage processing equipment. A 50 to 60% moisture rate is optimal for proper proliferation of microorganisms. Currently existing moisture sensors are classified in the electric resistance method and sensing moisturized air which is passively taken in through their wire mesh cover. Since these simple moisture sensors employ two electrodes imprinted on an uncovered insulator which continual cleaning of the sensor surface is required. For this reason, these existing moisture sensors can not be used for Garbage processing equipment. There are other methods, including the moisture regulated dielectric constant method and the optical method in addition to the fore mentioned method.

		There is no standard model number applicable for the Matsuo moisture controller.

		Matsuo defines an optimum method, sensitivity, and output numbers for load control in accordance to each application, and provide a quotation for an initial trial, followed by customized mass production. We will deliver a trial product within one to two months after receipt of your acceptance.

The following 3 points vary with each application, explaining why Matsuo does not have a standard model:

1. Definition for the sensitivity of each sensor
2. Output method
3. Encased type or open type (a requiring only circuit board)

Our proposal for each application is optimized based on the following points:

1. Matsuo is a specialty manufacturer which has been focusing on temperature control, and has accumulated a vast amount of basic moisture control technology through utilizing the same techniques of temperature control.
2. A best suited proposal of electrical features and cost is feasible due to the accumulation of both analogue and digital techniques.
3. A custom made moisture controller is available within one to two months based on points 1 and 2.

	Thermal timer (bimetal type dearly relay)

		The thermal timer is a delay relay which has a delay time of on delay/off delay. It operates within a range of 10~200 seconds, and it has an M contact (make contact) and B contact ( break contact). (On delay time: Delay time after the heater carries the current) (Off delay time: Delay time after the current to the heater is cut off) Because bimetal is the principle of operation, it will naturally be influenced by the temperature change in summer or winter. A bimetal for outside air temperature compensation is provided in order to minimize such influence.


BF, BA, BH type etc.
54.5x32x26mm etc.
Feature: •Both delay time and off delay time setting can be made by one thermal timer. •While auto reset is the standard, manual reset type can be made upon your request. •Any voltage of AC and DC can be accommodated. (Max. 250V) •Contact capacity is available in 3A, 6A and 10A. •Because of out side air compensation bimetal, operational time is the same for summer and winter. •Anti vibration and anti shock characteristics are superior compared to other types of timers. •Because all Matsuo thermal timers are housed in a dust free case, there is no contact error due to dust or other contaminants. •The price is low compared to other type of timer. •Because the B type has a sharp mechanism for repeated on/off, there is almost no noise observed. Application: ·For the automatic operation of boilers, coolers, copy machines, freezers, etc. ·As a delay element of home appliances. ·For the cutting off and resetting of over current for the certain period of time. ·As an automatic control program timer for automated machinery and industrial machinery. ·As a cycle timer. ·Wattage controller (It controls the duty of current by changing the ON/OFF ratio of the current to the electric heater)
